Funny how the social media section doesn't mention Facebook, which is by far more used here in Romania than Twitter/X, nor Instagram. For the latter the fediverse alternative is Pixelfed, for the former one could either use Friendica or make account on a Mastodon instance with higher character-limit - the one I use has the cap as high as 10,000 characters, so I can type long posts just like on Facebook, instead of just tweets.
When it comes to browsers, one could look into Zen Browser (the developer seems to be from Spain), Librewolf (possibly US-connected, keep that in mind), Floorp (desktop-only; developers seem to be Japanese), and for Android browsing probably Iceraven or IronFox.
Signal? What about Threema and XMPP clients?
