I’m one of the many recent immigrants from reddit so I guess that’s my start to alternatives.
I don’t think I can walk away from many of the American tech services I use, but what I have done is reviewed what I use, change what I can and walk away from what I can. I’ve curtailed my optional spend on American companies, goods, and services. We can all do that at least.
It might be scary, but not rearming may be scarier. If we’ve seen anything in recent history, it’s that two large countries run by leaders who are bullies care little for what you or I or anyone else wants.
