There are some other interesting ideas that aren't simply "invasive ads" or "subscriptions." Obviously, advertising was effective before the advent of the modern internet, so it seems like it should still be so if we rid ourselves of privacy-invasive hypertargeting and everyone has a level playing field (that being said, as the author and you yourself note, this does concentrate power in the hands of the best advertising "spots", e.g. Facebook or Google). There's stuff like BAT, which seems like it has a lot of potential but hasn't really taken off because most people just don't care enough about ads, and ads work well enough that there isn't sufficient motivation on the part of businesses to make it happen.
