They can all serve the same purpose. The advantages of 7zip are the following:

1. It is totally free (as both in free beer and free speach)
2. The 7z compression format is superior to rar because it can compress either more or faster (not both though)
3. The rar format is proprietary. You are free to decompress but not to compress. In a business setting, you could theoretically get in trouble if you don’t have a license. In some countries, e.g. USA, even outside a business setting. But if you have been using winrar forever, I can’t see you changing your ways anytime soon! :)

How can it be one? GNU/Linux, Firefox, EMACS, Ardour, Vitalium, SurgeXT, KX Studio (OK, this is repo), Carla, Gnome, Debian, MX Linux, XFCE, KDE Plasma, GIMP I am absolutely sure I am missing more s/w packages that I love but don’t come to mind.

Restrict the API to each server? (just joking!) Perhaps we can try being more polite and kind towards each other. I feel that this is the case so far. I fear the moment that “mainstream” users find out about Lemmy!

I love that it exists. I don’t visit Reddit anymore, although I miss some communities, especially AskHistorians and AskScience. Otherwise, I can tolerate the teething problems of Lemmy (and kbin) in order to support a free internet. The latter is far more important, to me, than “better functionality”

I am definitely less active on Reddit, to the point of absence from posting/commenting. However, I am not very active here either. I have encouraged others on Mastodon to join Lemmy but I acknowledge that it’s not as mature as a Reddit replacement, as Mastodon is as a twitter replacement. Definitely both systems are getting better and hopefully, we can move our social networking to the fediverse 100% by 2024.
