Good point! People get stuck in their ways. I have several friends/relatives who will on the one hand talk about how evil Facebook is, yet won't spend even a few minutes looking for an alternative social media.
I've tried (and I'll keep trying) but 99% of the time they don't even consider it, and 1% of the time I get someone to sign up, but they don't stick around. Facebook just has too much momentum for them. They have a lot of sunk costs into that platform. If they do go to an alternative, it's usually something dumb like Truth Social.
I guess they have little to no knowledge of where the future is heading to. Web3 is the next big thing, the earlier they climb onboard the better
