This person is trying to clarify that the problem isn't specific to Fandom, it is a general problem with our system of capitalism and will never go away until we change our system of economic incentives.
Basically, sell everything of value to make a quick buck is the guiding principle of our economy at present. It's the best way to get rich even though it ultimately makes society way worse off long term. We have to solve this on a fundamental level or things like Fandom will just keep happening.
Can we stop this capitalism boogeyman thing? Market economies don't force people to conduct business this way. We've had our current system for a long time and while corporate raiding has always existed the current epidemic is very recent. Its the result of a complex confluence of market, legal, regulatory and competitive forces that make it an ideal move for many businesses.
Fandom is unusually bad even in a sea of bad ad-laden websites.
