This is the mindset people should be having. Reddit is gonna be fine regardless of all this, and time will only tell if the Fediverse becomes big enough to be a competitor as a social media platform.
Truthfully, I was on the fence of leaving Reddit because of how much I didn’t like the hivemind there on the majority of subs. I still go on there for my niche and specific communities that aren’t on the Fediverse, but I pretty much just lurk there once every so often instead of actively participate - I instead actively participate on the Fediverse because the community is genuinely waaaaaay better than Reddit’s community ever was, even with the FOSS app gatekeepers here.
