This is about the feature in Gmail that allows you to setup so that Gmail automatically in the background fetch email from a 3rd party provider using pop3 into your Gmail account. It's not about accessing your Gmail account using POP or IMAP.

Um, no.
Just because you can reroute any IP on networks you control doesn't mean you can do shit on networks outside your control.

For example... If i setup a free wifi and let people connect, i can reroute the web traffic to my webserver. But no, that doesn't help me getting a valid certificate whatsoever.

Bazzite is part of the Universal Blue Project which are a handful of official images and also the base for custom images, they would have to duplicate the work from that project if they switch to something else.
Also, one of the main components for the system is "rpm-ostree" which is obviously rpm only but also seems to be quite Fedora centric.

Can always try LibreWolf, which is basically Firefox with Mozilla's crap removed.

And more RAM which was quite expensive at that time.

If the application+version you want is in your distributions repository it sure is awesome.

If not you have to pray there is a .deb file or preferably a 3rd party repository so you get automatic updates for your specific distribution+version.

If not you will have to try to install the .deb that isn't made for your specific distribution+version and then there are almost guaranteed problems with library versions not matching or other issues and there is nothing you can do about it other than compile it from source or well install one of those "pack" formats (which got their own problems).

For bitcoin that is correct. There are however other algorithms/coins were GPU mining is profitable or at least was.

It's a mess now with the free-to-play large map Warzone mode being a big hit.
They choose to merge weapons and operators (player skins/models) from the last 3 games into warzone.
So now you have modern, coldwar and ww2 weapons in the same game, with most of the ww2 weapons being the best. The newest stuff is always the best because then people are "encouraged" to buy the latest game for an competitive edge.

Giving taxpayers money to specific companies.

Not as long as we've got.
Two major lowlevel desktop systems (X11 / wayland)
Two major API/toolkits for creating applications (GTK / QT)
Basically infinite targets for applications (distribution+version specific packages, snap, flatpak)

Windows NT 4.0 that released one year after Windows 95 had the same shell but still lacked some other features like Plug&Play.
Windows 2000 basically merged the best features from Windows 9x and Windows NT into one OS for both home and pro/office users.
Guess they still thought home users needed another unstable 16/32bit hybrid since they released Windows ME 6 months after Windows 2000.

If you scroll down on your own link you will see it's not bitcoin that is mined. Currently DaggerHashimoto is the most profitable algorithm for that card. You just get paid in bitcoin on the site.
