Do you know anyone who works in design?
I do.
And quite franky, all of them would laugh in your face if you told them that fonts are something that ought to be provided "for free". Fonts come from designers, designers work hard and should be paid for their work. Accordingly, real professional designers pay for fonts -- by the hundreds or thousands, sometimes, so many fonts their computers slow down if they don't use special software to manage them all.
This is also why the strongest, healthiest software ecosystem exists on macOS. Because macOS still has that cultural creative core of its user base, a culture which believes that people who create things should be paid for their efforts. Accordingly, you can still release a commercial proprietary program on macOS and expect to make significant money -- even from a small user base. That's certainly not true on Linux and it increasingly isn't true on Windows -- except, maybe, for gaming.
As for the average person, we're not even talking about the digital world. Everything in print, everything written on television, uses fonts. And if they employ professional designers, those are going to be commercial fonts. The real deal, the ones that were first set in hot type by Swiss or Austrian guys a hundred years ago or more. Open source substitutes are no substitute at all.
