Why are you trying to make my view into some kind of minority?
Very likely because your view is that of the minority...
Show me some kind of proof that shows me in that minority.
I doubt there's hard "proof" one way or another. Or what would even qualify as proof.
But there's a lot of small details that build a larger picture.
First, most "gamers" don't buy the books. They play, but they rely on others for the rulebooks, typically the DM.
Second, and those "gamers" that do buy the rulebook seldom buy more than the PHB. There's a reason it sells far more than the other two Core rulebooks, which in turn sell more than any other accessory.
So already we have people buying accessories as a minority.
Of the people who buy the accessories, you'll have the people who buy all and the people who don't buy all.
Gamers are an obsessive bunch by their nature, so the percentage of fans that "gotta get it all" will likely be higher than in other hobbies. I'd
guess that the ratio of completists would be less than 50% of the dedicated fanbase (a minority), but if someone told me 51% of dedicated D&D fans bought all the books I'd probably believe it.
So fans who buy accessories are a percentage of the minority of a minority of D&D players. Right out of the gate.
Dividing that into fans who want more mechanical content versus more flavour text content will inherently further reduce the audience to an even smaller percentage. If people have an opinion at all: the fluff vs crunch division is a false dilemma; many D&D purchasers won't have a strong opinion one way or the other.
So, yes, your views are that of the minority.
Really, all our views are. Because the vast, vast majority of D&D fans won't even visit ENworld, let alone post on the forums.
D&D is doing very well. Very, very well. Likely better than any time in the last 30 years. And it's doing so despite the
constant complaints of lack of splatbooks. Which started pretty much immediately prior to the DMG being released when people wanted to know what was next.
So either the vast, vast majority of D&D players just don't care or the lack of new books isn't stopping them playing and supporting the game. Either way is the same for WotC.
