ML can be applied in a great number of ways. One such way could be content moderation, especially detecting people who use alternate accounts to reply to their own content or manipulate votes etc.
By including IP addresses with the comments they could correlate who said what where and better learn how to detect similar posting styles despite deliberate attempts to appear to be someone else.
It’s a legitimate use case. Not sure about the legality… but I doubt google or reddit would ever acknowledge what data is included unless they believed liability was minimal. So far they haven’t acknowledged anything beyond the deal existing afaik.
This asshole is just exercising his options to take money from the same moderators that were up in arms over his changes last year. Make no mistake, this is Spez’s revenge.
I really hope this whole thing backfires on reddit, but I think the reality is that it will further enshittify until it’s profitable, and it’s already so big it’s unlikely to fail.
Lemmy just isn’t a replacement and I think the nature of lemmy will stop it from ever being one unless someone throws godlike resources at one giant instance that federates with basically nobody.
