I don't really get what's evil about AI models and cloud sync.
And I don't think anything is wrong about Facebook's business model. I think most people are uninformed about it and believe that they sell personal data, but if you understand the way they make money, it's very difficult to say that there is any particular issue with it.
They take your data and turn it into something that has value to them. With actual selling, that something is money. In this case it could be something else, but saying it that way will not help the general discourse of this problem at all. Much like being pedantic over terminology.
