When it comes to the corporate world, your purchases are like your vote in politics. WotC has done some stuff that lots of people (myself included) don’t like. They’ve also done some stuff people really do like.
The situation around the open gaming license was the perfect example. People boycotted D&D beyond, and other directly related products, but very few boycotted the D&D movie, because people wanted to discourage Wizards from the specific license changes, but didn’t want to discourage making good movies for our niche audience.
Obviously not all companies have separate things like this. Activision/Blizzard are more monolithic, and so selectively boycotting them is harder.
All this said, there is no ethical consumption under capitalism, so if any boycott is costing you too much, monetarily, mental health-wise, etc., you shouldn’t feel bad for breaking it
