This is the type of comment that suggests you aren't engaging with what I'm saying beyond a superficial level. My argument is consistent. I'm not cherry-picking examples. The differentiator I'm criticizing is the personalized nature of the algorithms. But rather than engaging with the merit of that distinction, you're acting as if there is no distinction at all. I'm not sure if there is much point in contuning the conversation from there.
I think the other person's issue with your position is that the distinction is entirely arbitrary. You're not giving any reasons why the demarcation line for which feed algorithms are OK and which are not is there instead of anywhere else. It seems to be just "Facebook and TikTok are bad; Their feeds are personalized recommendation engines; Therefore personalized recommendation engines are bad, and other feed algorithms are OK".
