Downvote and move on, or provide the reasoning behind your claim. Simply saying "you are obviously wrong" without any substantiation adds nothing to the discussion and instead tends to derail it, prompting further low value comments or causing people to respond to a straw man of what they assume your reasoning is. You shouldn't assume that other commenters will know that your reasoning is expressed in comments by other people you haven't linked or referenced. Some of the other comments provided counter examples that aren't as obviously social media (YouTube) or corporate (BlueSky) and which I found less convicing than the clear analogue in Threads (which I have never used and just assumed worked like Meta's other products which don't allow this.)

After having looked further, I agree with your claim, but it wasn't "obviously true" to me. I only use a small subset of social media and thus the knowledge from which I operate is different from yours and different things are obvious to me.
