I'm anticipating that an ad-free version will be made available on educational or commercial licenses--or to home users for a nominal monthly fee. This mirrors the model used by Hulu, Prime, et al so there's a roadmap in place for it.
I'm with you re: FOSS OS migration. Some folks will but the majority will stick with Windows because that's what they do. It amazes me how many people think that Windows and MacOS are the only possible choices.
It's a drop in a very large bucket that will never be filled, by design.
