I think you are partially right, but I also think that people are willing to participate as long as it's low effort relative to their consumption or the expected value warrants investing more effort (i.e. why many teens want to be influencers).

Adding a heart reaction to an Instagram post is much easier than creating that Instagram post, though Instagram has made this very easy to do as well, which is easier still than creating a YouTube video, which is easier than updating a web page on SquareSpace.

I think this is why Reddit is mostly lurkers.
