Let's start with this - what is the purpose of writing in traditional forms and meter? According to Preface to Lyrical Ballads, it is a poetic convention which is fundamentally pleasing to the reader. It is easy for the reader to follow, predictable, and pleasing to the ear.
...the metre obeys certain laws, to which the Poet and Reader both
willingly submit because they are certain, and because no interference
is made by them with the passion, but such as the concurring testimony
of ages has shown to heighten and improve the pleasure which co-exists
with it.
I read a recent article that pointed out that, while many leading poets are abandoning meter and traditional forms, the poems that are most popular remain by a huge margin ones written in meter and traditional form. However, it is important to note that by popular this article included many people who don't read poetry on a regular basis, so although these people have read some poetry at some point in the past and can give an opinion on their favorite poem, these people are for the most part not the ones out there buying poetry books and showing up at readings.
So there is, on the one hand, the opinion of a general public who do not vote with their wallets or their time to support poetry in any way, and then the opinion of what The Atlantic in 1991 described https://www.theatlantic.com/past/docs/unbound/poetry/gioia/gioia.htm:
AMERICAN POETRY now belongs to a subculture. No longer part of the
mainstream of artistic and intellectual life, it has become the
specialized occupation of a relatively small and isolated group.
Little of the frenetic activity it generates ever reaches outside that
closed group.
...
Decades of public and private funding have created a large
professional class for the production and reception of new poetry
comprising legions of teachers, graduate students, editors,
publishers, and administrators. Based mostly in universities, these
groups have gradually become the primary audience for contemporary
verse. Consequently, the energy of American poetry, which was once
directed outward, is now increasingly focused inward. Reputations are
made and rewards distributed within the poetry subculture. To adapt
Russell Jacoby's definition of contemporary academic renown from The
Last Intellectuals, a "famous" poet now means someone famous only to
other poets.
...
Daily newspapers no longer review poetry. There is, in fact, little
coverage of poetry or poets in the general press. From 1984 until this
year the National Book Awards dropped poetry as a category. Leading
critics rarely review it. In fact, virtually no one reviews it except
other poets. Almost no popular collections of contemporary poetry are
available except those, like the Norton Anthology, targeting an
academic audience.
The full article is well worth the read. It goes on to describe the decline of verse (the correlation between how poets used it less and poetry became less popular with the public), the situation today where there is so little attention paid to poetry outside a specific subculture which is increasing introspective, and that there is a very large amount of bad poetry that is getting published today.
Seven years later, in 2009, Newsweek reported that poetry readership had fallen to a new low.
In 2015, the Washington Post reported that:
Some people are still reading [poetry], although that number has been
dropping steadily over the past two decades....
In 1992, 17 percent of Americans had read a work of poetry at least
once in the past year. 20 years later that number had fallen by more
than half, to 6.7 percent....
Some numbers that speak to that point -- since 2004, the share of all
Google searches involving "poetry" has fallen precipitously. Today,
poetry searches account for only about one fifth of the total search
volume they accounted for ten years ago.
Within the subculture that exists, there is a strong opposition to writing poems in form, as this article from Poetry Foundation explains https://www.poetryfoundation.org/articles/89288/why-write-in-form:
In poetry, one of the best ways to practice technique is to write in
traditional forms. But for many writers—and I’ve been guilty of this
as well—this notion can elicit not just avoidance but also outright
opposition. It’s easy enough to look at the current literary landscape
and say there’s no point to practicing these old forms. Most journals
don’t seem interested in publishing formal poetry, and though there
are some fantastic poets working in form today, they are in the
minority. Even when there is a resurgence of interest in form (such as
New Formalism), it’s seen as an outlier, even reactionary.
The distaste for traditional poetic form and techniques by some notable writers has influenced other writers not to completely abandon these techniques, but to hide them so they're not so obvious, as explained in this New York Times article on Margaret Atwood http://www.nytimes.com/books/00/09/03/specials/atwood-oates.html:
... like many modern poets I tend to conceal rhymes by placing them in
the middle of lines, and to avoid immediate alliteration and assonance
in favor of echoes placed later in the poems.
So, in summary, yes, there is a preference among the subculture, as detailed in the Poetry Foundation quotation above, and that preference is strongly against poems in form (though there are exceptions and some publications which only publish poems in form). At the same time there is an opposite preference among the general public, but they've tuned out.
