They are objectively bad for some definitions of bad. What do you want for them? Universal respect? Just because taking something good and making it shitty is one way to make money doesn't mean that it is the only way to make money.
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.
I think the point is that if we want this to stop happening, we have to address the cause of the problem, not just complain about its effects.
