Dismissive, yes.
Buying various tools for a craft does not make you a craftsman. You only become a writer by writing, not by buying silly hipster products "for writers". And there have always been such products aimed at people who don't actually write.
Uncharitable, no.
Some people want to "be a writer" for various reasons without actually wanting to write. It's anything from an imposed expectation (common in "creative" subcultures) to an affectation. If playing at being a writer makes them happy, that's harmless. There's no stolen valor in pretending to be a writer.
But, some of the people buying these sorts of products could be writers. Very often, they buy these products out of fear, that being one of the major factors that inhibits writing. They're afraid to write because they're afraid of writing badly, not understanding that even the greatest writers had to write many thousands of words of utter shit in order to develop their skill. (And not internalizing that even great writers revise, rewrite, and get the help of editors.)
So they pursue methods of making their writing environment more optimal, buy various tools, or read endless books, magazines (back in the day), or blog posts on how to write—and when they try each new gimmick, they find they're still afraid. Obviously, then, they haven't tried enough and haven't optimized enough, so they go on to the next gimmick.
It can be very hard to get over that fear. Writing can be a lot of effort. But getting there is much more satisfying than hanging back and trying to find the key to being a writer.
The key is just writing.
Published, unpublished, printed, made a cheap Amazon ebook, hosted on a free site, posted on a forum, emailed to a list, shown to a few friends, safely squirreled away on your hard drive for nobody else to ever see? Novels, short fiction, flash fiction, fan fiction, slash fiction? Blog posts, essays, books? Deathless prose or complete dreck?
Doesn't matter: you wrote. You're a writer.
(And yes, to be entirely fair, I don't actually think anyone has "nothing to say". But you have to actually say it, and these things can't squeeze that out of you.)
