infosec twitter is crap like any other twitter subculture, full of drama queens and clickbait to increase their fav/rt count. What's even sadder is that they make no money off it.
I've seen that. In my small town, taking the bus is free for senior citizens. So they sit there all day and socialise because they simply have nothing better to do.
That's a big problem there. Mastodon seems to be a EU thing. The bigger instances should consider hosting in a place with free speech. It makes no sense, imagine if all instances were hosted in China.
Personally, its price. I would never buy an Android and I don't want to pay full price to own an iPhone. It sucks that you've got to be wealthy to have privacy and security. The small screen blows, though. (That's not to say I like big screens, but 4.7" would be so much better...)
