Flatpaks follow the concept "losen the sandbox as much as needed to make apps work". This sucks, in constrast to android, but its needed.
So you shouldnt need to edit anything via Flatseal/KDEs settings, if you want to make apps work.
Flatpak is default on OpenSuse too, even more as they use Flathub instead of the Fedora Flatpaks repo. RHEL is just trying to get some money and stop people from using their work, as they need to make money.
Honestly it should be normalized that people on FOSS do weird things to make money. Fedora is RHEL upstream, so RHEL is not stealing any code, just take what Fedora does and wait a bit until its stable.
Appimages are completely flawed and as an apt user you should not like to use them, at all. This post of min may give some infos, I will update it soon.
Sounds like an overcomplex and invasive solution for an easy problem. Just switch the number, obviously some strange people (and a lot) had access to it.
Then follow with best practices and never give out your phone number when possible. There are tons of free sms services you can use
Yesno. Snaps are not sandboxed at all, which is a nogo for normal application distribution.
So while I think it also sounds nice to pack an OS into different immutable parts, if the entire system is flawed, its not worth it.
Flatpak is good for app distribution, the rest is job of the OS.
not rolling release but normal stable release, not some random LTS. Not every software is like Firefox ESR (which honestly is not needed as Firefox doesnt break), but Debian etc. often just randomly dont ship updates.
Fedora is a bit too rolling, but if you always stay on the older supported version, thats okay. Especially with atomic.
Downstream Distribution is simply very very work intensive. By having the system and apps come from a downstream origin, packagers need to follow upstream and keep up with versions. And as upstream doesnt officially support these packages, many will have bugs. Or like on Debian, packages will be unusable as they are too old with unfixed bugs for years.
Neither Android, nor Windows nor any other big OS do things that way, for a reason.
Just putting "personally" in front of an unfounded statement doesnt make it better
