From a practical standpoint, the country that hosts many digital services is undergoing rapid political change. For awareness of non-US alternatives, check out:
PeerTube seems fine for a YT alternative (only because it's pretty much either it or Odysee, that's what happens when you have an effective monopoly on user-generated content like YT does, and PeerTube IMO needs to take off sooner rather than later given how ridiculous YT's censorship has gotten lately), and then of course Lemmy (this platform) is looking really good so far as a Reddit alternative and I've only been on it for a day now, ditto for Pixelfed as an Instagram alternative.
And then of course there's Mastodon for a Twitter/Facebook alternative.
Also, Matrix seems fine for a Discord alternative, but moderation is all over the map.
Proton is still a great product.. easy to switch away from Google, especially if you don't have the time to self host or manage the complexity of 5 different services.
I am aware of recent discussion, and have decided for myself that overreacting is not necessary, though that's up to you :)
Nowadays I half suspect any tech CEO to have some questionable mindset (to say the least). So it seems more important to me, what the company actually does.
I hope everyone complaining about Proton now also does not use Google, YouTube, Facebook, Instagram, X, Apple products, and the list goes on. Their CEOs are definitely a lot worse.
Yeah it could be argued that Fastmail is less private than alternatives, but they make a damn good service. Plus email shouldn’t be used for secure communication anyways.
