Ah, it’s been a while since I used ChromeOS. Looks like Flatpak was founded about the time I stopped.

Ah, it’s been a while since I stopped using ChromeOS. That’s an improvement.

Most Fediverse stuff has web front ends so that any modern browser will work.

My concern would be that Chrome is about to neuter ad blockers, and you can’t use a different browser without replacing the OS.

Both are also heavily privacy destroying.

I’m not sure that there is any point in a fediverse platform. That implies you want interaction (e.g. comments) from other locations, and therefore need moderation etc. A local blog site with ‘share to Mastodon’ buttons (if they exist) is probably all that’s needed.
