So, not to highlight your post, but to point this out; of the numerous examples I gave, your response was, "Well, yeah. I care. I don't buy VW products."* And the stuff with Wells Fargo has been well-known since 2016 ... they just keep happening. If you really wanted to disentangle your finances as a statement, you would have by now. The reason you haven't is because ... it's hard. I'm not blaming you, by the way ... corporation do a lot of questionable things, and choosing between various corporations isn't about the choosing the virtuous so much as choosing which is the least evil.
But your lack of action is the exact point I'm getting at. It's very easy for people to announce their outrage- all you have to do is type it. It's harder to act on it ... but acting on it is really, really, really easy in some areas. "I won't buy VW products," isn't a big deal given that there are a number of car companies to choose from, and purchasing cars is (for most people) not a regular activity. It's even easier if, for example, you were never a VW shopper in the first place.** We talk about voting with our wallets- and this is important. But unfortunately, most people don't actually live this. They vote, every day, with their wallets by buying the cheapest product on line.
So I want to get to the last sentence you wrote- obviously, it does matter to some people. Everything matters to some people, and acting out on outrage by typing up screeds is relatively painless. But I'm not sure I agree with the second part (the people for whom it does matter tend to be loud about it). .... I mean, partly? Obviously, if you are a 3PP and this is causing you uncertainty, I would expect you to be vocal about it.
But based on these threads, a lot (and I do mean A LOT) of the people that are being the loudest and most gleeful about this are the people that I know have already trashed WoTC and/or 5e and/or 5.5e in these threads prior to this. People that didn't like the way that D&D was now a more progressive RPG. People that didn't like the lack of crunch in 5e. People that still were bitter about WoTC abandoning 4e. Sure, that's not everyone! There's a lot of 5e fans that aren't happy, and some are outraged and very vocal. But ... it does seem that we have a lot of people screaming that they'll never play D&D again, with the unstated earlier premise (and I stopped playing a few years ago, and I am so happy to see them go down for reasons!).
*VW is, of course, more than VW, but it's still pretty easy to avoid, especially in the US.
**This whole issue with corporations is also matched with being a fan of certain artists- hence, the "problematic fave" category.
