At least telegram has foss clients.

I don't like saying it but: Snap within a distrobox?
Telegram and reddit are weird choices nowadays for a new project.
If you want to tinker with the system, if you want to install multiple DEs, if you want to test and change things on your own, you may not like the rigidity of atomic systems.
If you don't want to tinker with your system and you always want to have a working system, go for it.
In the future it will become easier to tinker with the system (I hope that it doesn't take the path of android). I hope that more happens within containers and that it mature even more. Maybe the de within a distrobox? That would be awesome but I don't no the downside of it.
Right now you are still an early adopter. It sounds like the future and for many it will be, but who know what's next. Especially companies have an interest in fedora's atomic distros with ostree.
Good question. With 16 GB RAM 8 haven't seen RAM issues for normal stuff
That's a fairly good point. On mobile startup can be crucial because sessions are short in comparison to desktop where you have longer sessions and startup time is negligable (even the slow startup times of snaps could be ignored for e.g. a video editing session)
Low specs shouldn't keep the community from moving into newer technology.
What's the catch?
Kde has many things baked into the settings that gnome hasn't. GNOME is just more beautiful (and has PaperWM which is why I have to use GNOME)
You only need flatseal on GNOME. KDE has it baked into the settings
This should be pinned somewhere https://blogs.gnome.org/wjjt/2021/11/24/on-flatpak-disk-usage-and-deduplication/?ref=ypsidanger.com
Edit: the speed shouldn't be a real issue. You may measure a difference but that's not an issue as it was with snaps until they improved upon it.
How?
