I added this as an edit, but I think it’s fair to reply, I agree to the disagree, for fun I ran this through GPT just to see what it’d say. Not that I would trust it to be correct ever, but it’s interesting getting an “outside opinion” about this.

I’ll paraphrase the wall of text, but it looks like we’re both honestly correct. (If we trust chatgpt)

Right now, there is no law specifically for this scenario, so it will go unchecked until it gets challenged in court. In court, they will usually go off of the first place a user signed, so in this case lemmy.world, with the caveat that my server can override that if terms are presented and accepted by you, the user. There is no mechanism for that, so it would probably lose in court. However, the enforcement of such is pretty much nil, and getting it to court is a problem by itself.

So, I think we’re both right. I think you are right in terms of what should be happening, and the laws should be expanded to include federated content, and I think I’m right in that it’s impossible to expect privacy until the law catches up and puts it in writing.

One important thing for you, specifically though, is that your link at the bottom is more or less useless. All of these are based on the server, your server owner’s rules are what matter, what you leave in the comment does not. So if you chose Lemmy.world because of how they handle user privacy, awesome, that’s what will hold up in court. A license in the comment from what I see, probably will do nothing.

Anyway, I agree, we can leave it be. The only thing I’d encourage for you is to not trust that anything you put here is private or safe, this is not a walled garden, even if it’s not legal anyone can have a server and be listening to our data, or training, or whatever. Just, be careful what you put out here.
