If I'm being honest, most "content" I've come across on the web doesn't deserve to be funded and its creators are better served creating something else if they're looking to be compensated.
people will create because they want to create
What great content I have come across is usually created within a similar ethos to FOSS. People know they've learned a great deal from others in the past and want to pay it forward, or they want to share something with the world to see how others might iterate upon it.
if the content is actually good, people will be willing to pay for it--probably even if not forced to do so: lots of content creation is being funded by donations right now
I've also seen great content from people connected to a patreon, so there is definitely room for compensation, if the content is good enough.
