at least you could keep their reviews so users could at least know if the app can be trusted.

You mean, don’t trust a flatpak uploaded by a random person, but if there are enough fake reviews, it can be trusted?

Also the location of known Wifi networks.

I still think Ubuntu is the best option (particularly if you want to use the non-LTS releases)

Having said that I do hate snaps and also dislike flatpaks. So what I do is just use the Firefox deb package from the PPA and the chromium package from Linux Mint. Oh, and I have actually replaced ubuntu-advantage-tools with a no-op dummy package.

“secure alternative”? Others are not secure?

“they put ads in the terminal” isn’t really accurate.

Their “ubuntu-advantage-tools” adds information to one of their other products to the output of apt. You can easily get rid of that by uninstalling/replacing “ubuntu-advantage-tools”. It’s definitely not like they are selling ad space in your terminal to third parties.
