Isn’t that mainly just torrent trackers that publish your IP address and then the ISP gets a request for who was using that particular IP address. I don’t think an ISP would itself be interested in detecting whether their customers download illegal content - there is no business case for them to do that.

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.
