It's good to see the subreddits fight a bit, but the internet of today is not the liquid ever changing space it was 10 or 15 years ago. Websites like reddit facebook and twitter are full on mainstream. Their userbase is huge many of which lurkers who dont pay attention or engage with a lot of the content.

Reddit especially is so compartmentalized that they helped kill off message boards and are essentially a series of small esoteric forums into themselves. At the end of the day there is a lot of value in being able to get pretty much any hobby and find a little active community for it and that really cant be replicated elsewhere. Much like how Facebook has been controversial for years the exodus did nothing because for a lot of people facebook is the internet. Twitter is a cesspool and even the mainstream is clowning on it, and yet it still lives and thrives.

There will be a bit of an exodus, but many of those people will likely begrudgingly go back home to reddit, and even for those that go away forever there are enough users that wont notice or care. Heck look at the new reddit/reddit mobile fiasco. A lot of noise and lots of "Im never going to use anything else". In spite of that you see tons of people with avatars and newreddit style profiles, and you see lots screenshots shared showing the official app and people outright surprised that there even are alternatives when they complain about it. Reddit is too big to fail.

That said enough people will leave and seek alternatives to finally kickstart alternatives in a serious way. I know Ive taken a look at lemmy in the past a few times but upon exploring found instances with double digit monthly user counts that were mostly dead. I dont mind a smaller site and in fact reddit got too big a long time ago, but it needs to be semi active and Im not interesting enough to do it myself. The threats alone have added quite a few users already.

Reddit wont die it will burn on, but the embers it sheds thanks to these events will finally ignite other alternatives.
