But who is supposed to trust whom?

12 years old and still relevant:

I settled on two.

1. Arch for my desktop, because there I like having an always up-to-date system with the latest drivers and libraries so that I can always try the latest versions of whatever it is I want to play with next. Pacman is also a pretty good package manager, and almost any piece of software that is not in the default repos can be found in the AUR. For the rest, I also like that Arch just gets out of your way and lets you configure your system how you want.

2. Debian for anything that runs unattended, like all my homelab services. It's well tested, offers feature stability, has long-enough support, and doesn't do weird things every other release like forcing snaps or netplan or cloud-init on you. Those "boring" qualities make it the perfect base to run something for a long time that doesn't scream for attention all the time.

Never knew I needed Kaylee in a Star Trek mini dress, but here we are.

I think you're missing the point here. The solution to the "documentation on a chatroom" problem is not putting documentation on another chatroom.

It can be done with shreddit: https://github.com/andrewbanchich/shreddit

It has a built-in option to point it to your extracted GDPR data, and will edit and/or delete all the comments that are listed in there.

Just configure it according to the instructions, and then let it run unattended for a while. It took about 15 hours to delete the 13000 comments on my 12 year old account.

Technically, Lemmy could go the same way. Even though it's an free software project, @ljdawson doesn't own the Lemmy trademark. I think it would be prudent to call it "Sync for Lemmy".

Also, the name change from "Reddit Sync" to "Sync for Reddit" happened long enough ago that people are probably more familiar with the new name,

How good is the performance of that on a rpi4? Does it work for transcoding videos?
