I don’t think the arguments made by you and OP are mutually exclusive. Facebook is a rotten company and we shouldn’t even be using their website, let alone paying them for the privilege. But Websites aren’t free to operate, Ads are toxic, and we shouldn’t let Ads be the method by which Websites pay their costs.

If OP weren’t posting their argument in a thread about Facebook, but Lemmy instead for example, I think your read might be different. Their last sentence, to me, indicates that they agree with you.
