Let me try to offer a slightly different perspective. I won't even try to speak for the folks who actually don't want such changes to occur, but I think it is a misunderstanding to think that anyone who doesn't like every single change that is implemented is inherently against the underlying goal of those changes (that is, towards inclusiveness, etc). I think what some protest is A) The broad-brush through which things are labeled as racist, sexist, etc, and B) Any erasure or re-writing of the past, be it older products or even older gamers and game designers, without understanding the context of the time in which it was published, or said people grew up.Huh?
So, WotC's slow steps towards inclusiveness, avoiding systemic racism and sexism embedded in their products, is somehow disrespecting the OSR crowd? Only the ones who don't mind racism and sexism in their gaming, I suppose. I'm okay with that.
As for A, what is and is not racist, sexist, etc, is not set-in-stone. Meaning, just because someone cries "problematic," doesn't mean something is what they say it is. Otherwise there's a danger of getting rid of everything, because anyone can cry "problematic." Not only is our understanding of such things in a constant state of change, but there is no one-size-fits all understanding of what is or is not problematic, racist, sexist, -phobic, etc.
As for B, this is a common error that people make: applying current views to the past. We do it all the time with our family and ourselves, even. "I was so stupid back then," seemingly without realizing that one's 20-year old self shouldn't be judged by the same criteria as their 40-year old self. Everyone has a relative that uses cringeworthy words and phrases that are no longer considered acceptable, at least by many. But assuming that a 75-year old means the same thing when they use a certain word as if they were 25, lacks any understanding of history or context. This doesn't mean that it is OK, just that it is important to understand the context in which that 75-year old grew up.
(This happens all of the time with my 79-year old father. He's a very liberal guy, came of age in the 50s and 60s and embraced the socio-cultural zeitgeist of the time, but is still a product of his time, with certain biases and assumptions that I certainly don't have, and that wouldn't be viewed as acceptable by most younger folk).
Or to put it another way, a lot of such (older) folks aren't opposed to greater inclusivity and such, but just don't understand and/or agree with every interpretation or change. To use my father as an example again, he's often surprised when I point out that something he said is no longer considered acceptable. It isn't that he is resistant or wants things to stay the same, but that he doesn't mean it in the way that the newer understanding implies.
And of course WotC has to find the balance. They don't want to "cancel" the history of the game, nor do they want to exclude old school gamers as a whole, but they also recognize the changing demographic. So while I expect them to continue to move in the direction that you're saying, I do think that some skillfulness and care should be taken, and that they shouldn't fall into the trap of addressing every little grievance or complaint that comes up, but be somewhat measured in how they proceed. Or to put it more simply, they need to find a path somewhere between the extremes on either side, of "change everything!" and "change nothing!"
