There will always be bottom-feeders as long as there is a market where people are not forced to choose with their wallets. Killing the "vast majority of content on the internet" seems like a good thing to me, honestly.
I am reasonably sure that even if our preferences are complete opposite and we eliminate 99% of content in general, you would still have enough quality content for what your interests are. But just to be extra sure, please vote with your wallet and actively support the things you like and don't let advertisers do the choosing for you.
