I agree with you as someone with an Nvidia card. I do want to get an AMD GPU when I upgrade, but to claim that I should just throw out hardware I’ve already paid for is absurd. This proposed “solution” is very unproductive, especially if you bought the hardware to use with Windows or another, less strict Linux distribution.
Don’t feel too bad about your hardware and just make a more “libre” choice in the future. You aren’t using Windows or Mac anyway, which puts you leagues ahead of other users.
On a lighter note, Nouveau will be able to boot with your card in Fedora 32. Of course, Nvidia is still proprietary and you’ll have to use their drivers, but you will have a GUI at the very least. This is all coming from someone who has an RTX 2070. Again, if you are upgrading your GPU then I wholeheartedly suggest AMD on principle alone, though I don’t have an AMD card, but don’t feel bad about a decision you made a while ago.
