A lot of the people coming in right now are specifically protesting Reddit due to the shut down of their preferred third party apps, especially Apollo, an iOS exclusive. Android has Jerboa and PWAs, but on iOS we just have the site (and mlem, but it’s very early days there). I think that if/when old Reddit gets shut down, the resulting exodus from that will not care as much about app access, as they were using the web previously.
Won’t most countries require you to have a degree in order to immigrate there? I generally agree with what you said otherwise, but as a tech worker with lots of experience and no degree, I think it’s limited my options for leaving the US, while otherwise being a good move overall.
