Academic publishing is in a very weird place and is very, very political. Its true that authors have to pay to have their papers published in most journals or conferences after they’ve been accepted, but like all things academic, this is highly dependent on the field. Some universities will reimburse professors publishing costs, others need to pay out of pocket or with grant/public funding.
While its true that there are open-access journals and conferences without such costs, I would wager that most well known researchers would avoid such avenues of publication due to prestige. The larger journals and conferences have review boards where the top scientists in the world sit on them. As a potential published author with such an outlet, its a great honor to even be considered. Most researchers don’t want to take the risk of going with a less prestigious outlet if it will run the risk of smearing their image or damaging their ability to publish in better outlets in the future.

If you’re running Debian stable, your hardware was probably too new for the kernel. Unless they changed their development paradigm when I last ran it, stable is always 2-3 years behind mainline Linux software aside from security patches. It’s one of the key reasons why it’s so stable.
It sounds like you’d be better off with a DE or WM that isn’t gnome. The GNOME Project has been progressively sticking more and more of the customization features of the DE behind either gnome tweaks or the command line, likely to unify the experience for all users and improve the ability to provide support.
Personally, as far as gnome-based DEs are concerned, I prefer cinnamon, but I’m fine running Mint to just have it come pre-installed. I don’t know what dependencies it pulls in now if you install it standalone from Mint.
