Nobody must watch ads, that's the point

Businesses that rely in it don't have an innate right to exist. It is ok for some businesses that are viable now to not be in a future, better world. It's ok for some people who are rich now not to be as a result of that.

It's ok for there to be less total content, too. Perhaps that's even desirable when so much is bottom of the barrel stuff (and sometimes 100% a net societal negative) because that's the only way to fund something with a handful of ad views.
