I don’t have a problem with snaps as a technology. If you want to use them, then who am I to judge?
But what I do have a problem with is when I don’t have a choice and I am being forced to use what the distro maintainers think is good for me. That is what finally made me quit Ubuntu and switch to Fedora.
Facebook Marketplace is pretty good though, at least in the US. All other Facebook features are rubbish
