The topic is
No, that’s not the topic. The topic is ads being placed in the fediverse in a way only defederation could block. Even if Meta silently making posts in the name of my favorite organic orange juice advertising Coca-Cola was legal (it’s not), it would be easily solved by simply not following any Threads accounts. Also, Lemmy cannot interact with Threads anyway, so Lemmy servers defederating from Threads is completely pointless.
about them impersonating their own users and using that to push ads through federation.
No, that’s not legal. That would violate copyright, consumer protection, competition laws, and whatnot, at least in the USA and the EU. Mastodon users (!!) must be explicitly aware that a post is an ad, not the brands ticking off an EULA on Threads. Therefore Mastodon users could decide to follow a brand account were products are promoted (just as they can right now if that brand has a regular Mastodon page) but Threads cannot legally impersonate one account on Threads to advertise another account. That’s not a grey area.
I didn’t set a timer but it took me at most a single-digit number of minutes to find documents and announcements about the FTC tightening the rules about deceptive advertising several times throughout the years.
Considering that I’ve replied to another person with my explanation and got very positive feedback, I certainly know better than you. You’re not the person I’ve replied to. You interjected and then tried to educate to me what my comments are about.
Any brand account on a regular Mastodon instance would be the very same.
Mastodon doesn’t have an algorithmic timeline, so that would lead to absolutely nothing.
Relevant to the comment I’ve initially replied to.
Nope.
No, I made several good arguments, you just moved goalposts and declared they don’t matter.
