The problem is there are alternatives out there and some people are using them. There is nothing making people use Twitter. I get the impression news and entertainment media are the only people still using it. If they start kicking more people off Twitter or restricting them, it should just drive more traffic to other sites. People seem to be willing to put up with a lot to keep going with what they are familiar with.
I have slowly been adopting alternative video apps. Some people I follow are on Rumble. A few are now on Utreon. I heard some are on Odysee, but I haven't signed up there. All of them have phone apps and work well enough. Utreon allow guns on livestreams which is nice to see since youtube banned that a while back.
In theory I agree with you, but the "big" big tech guys are just too entrenched. I too, attempt to use alternatives, but those big guys are just so overweighted that it's difficult to use alternatives. Half the time that I do something like search for local contractors or businesses on duck duck go, I end up switching to Google map search to get a larger result plus the google reviews, which I have to say are, unlike Amazon reviews, actually helpful.
Other than using Twitchy to get myself worked up about stuff, I don't touch Twitter at all, and I have no facebook account and only use facebook for some stuff, like up until they recently wised up, my LGS had their main presence on Facebook, so if I wanted to see what was new or on sale, I would have to go to their stupid facebook page.
Just like a lot of the internet gun guys that started with youtube channels still have a great, if not predominate part of their content still on youtube because nobody is going to Rumble because Rumble has such sparse content, which, admittedly, is kind of a "chicken and egg" thing.
