Idk how you exploit content. It's ussually the creators that get exploited. The idea is you put the content out there and put an impression on people so eventually they start thinking about them think about comming to Lemmy. I got nothing if you don't want to support x or twitter by crossposting from Lemmy.
I still say Lemmy/fediverse needs to build more niches community's up more than it needs to market so that way people stick around or engage more, so people don't drop off the platform from boredom
I know Instagram puts it's content on Facebook to get people to sign up for Instagram. I know they're both meta.
It's pretty intrusive, but it's evidence that it works.
But I'm more on the lines of make more features
