From that point of view one could argue broadcasting Tour on public TV in most of Europe isn't free either:

But in reality it isn't perceived like that. Even if and when some sport is moved to some sports oriented channel on cable TV, on where a reasonable monthly fee is required and most households in the country have access to it. That is still rather OK-ish. Moving some sport to some special TV scheme, on where most households in the country don't have access to it any more, due to high cost. If it would work like that world wide, then forget about the Tour as being a thing. That is once the existing audience is milked, presumable middle age men, then it's mostly over.
