But all user contributions on StackOverflow licensed under CC BY-SA 4.0... right?

They announced a Steam version few years ago, but there are no news on this since then.

Sounds like trouble for Newpipe, Sponsorblock, etc...

SponsorBlock isn't affected at all, as I understood after reading an article. Why did you mention it?

And the CEO of that company wants us to "be comfortable" with not owning games.

But Google is likely trying this dark pattern to sway people away from F-Droid or alt stores by making users uninstall these apps and install it from the Google Play Store.

No, it's the security measure. Anyone can use existing package ID. If the user installs a different app with the same package ID as the other, that new app just overwrites the old app and will have access to the sensitive data of it.

F-Droid apps are built and signed by the people at F-Droid. Apps from Google Play and GitHub are built and signed by the developers themselves. You can update Google Play apps from GitHub and vice versa. That's why I use Obtainium over F-Droid.

Even worse, Thunderbird doesn't save data in ~/.mozilla/thunderbird, but in ~/.thunderbird.

Developers don't have to support Linux natively because Proton does the job very well

Most of subreddit admins and mods are not interested in migrating to somewhere else. A few months after API changes Reddit is still usable and active. Even third party apps are functioning if you apply a patch with your developer token. Also mods don't want to lose their power.

If you really want to bring more official communities here, you should ask admins who are already interested in open-source or Fediverse. For example, I found that people behind Fossify (a Simple Mobile Tools fork) had created a subreddit. Ask them about Lemmy. It's FOSS-friendly, there are a lot of fans here, so the chances that they'll make and promote a Lemmy community are much higher.

Codeberg and other alternatives are used by 2 people, if not more. If a repo is hosted on such unpopular service, potential contributors must register a new account. This is very frustrating if you want to report just one issue or make one pull request. Self-hosted repos are even worse.

This problem can be solved by implementing federation. GitLab, Gitea and Forgejo already working on it, but really slow.

You've already defederated lemmy.world and sh.itjust.works, so I don't care

Yes, you can enable it in your the LibreWolf specific UI or in your overrides. There aren't significant downsides as Firefox Sync encrypts your data locally before transmitting it to the server. Additionally, you can self-host the old version of the server if you really don't want to use Mozilla's, and there's work being done to have the new version equally easy to self-host. Find out more about the technical details of Sync's implementation here and here.

When using Sync across multiple installations you might want to disable settings synchronization to avoid unintentional changes.
