I do think you are overreacting a little bit about people being potentially invested in the fediverse/invested in trying to find a different home to replace reddit. It's not a bad thing for people to care and be unhappy about the way their reddit forum is being run. Without any emotions at all, there can be no actions or changes done anyway. How would people have transitioned from diggs to reddit if some core users weren't upset enough to test the waters with reddit?
People want to avoid and use reddit less because they don't approve of the way the company is running their product. If you don't feel uncomfortable using reddit, that's great, and you absolutely should just use either/both the way you enjoy it. However, it seems like your argument is that no one should be unhappy to the extent they stop using reddit, and I feel like everyone can have products they don't want to buy anymore due to their internal ethics. It's just a human thing to do to.
