In the OF/pet rock/pidgeon trio, the pidgeon is actually the odd one out; the other two are all about making money by exploiting people's need for socializing.

Alas, "e-celebs" are a step worse than "e-prostitutes". Both exploit parasocial relationships to trap customers, but in the end, OF performers provide customers actual value in exchange for money, while vloggers and influencers also try to sell you all kinds of random shit - their actual business is advertising.

(It's similar to analog world prostitutes vs. telemarketers; the former engage in voluntary exchange of value for money, the latter just try to scam you. That the society scorns the former while accepting the latter is some perverse inversion of morality, if you think about it. One could argue that the value prostitutes provide is poison - but then so is what telemarketers sell, too, and prostitutes don't cold-call you to trick you into buying.)
