Users will stay no matter what. When was the last time you saw meaningful exodus off a major platform? The Reddit to Lemmy, or Twitter to Mastodon migrations were the largest in decades and they had almost zero impact on the number of visitors to the origin sites. The days of Digg to Reddit are gone. Average users don’t have the patience or attention span to build communities anymore, especially not when whatever they build will eventually be heavily monetized, changed beyond recognition, and generally enshitified.
