While it is clearly a shitty move, it's not really clear to me that posts on Reddit consist of personally identifying information as protected by the GDPR.
Every post is tied to a username and email address, making it personal information, since each poster can be identified. I'm sure they're also tracking further metrics such as IP addresses, browser fingerprints, etc. It is immaterial if we from the outside are able to identify users, it only matters if it's possible given the data available to the processor. In this case, it is. Not to mention, there is a good chance texts and posts themselves contain plenty of personal information, such as linking to other user profiles, mentioning and discussing people, etc.

If they were GDPR-compliant before, I don't see how they've changed to not be GDPR-compliant now. They allow people to delete their accounts and their posts if they wish, which removes all identifying information from their system.

Frankly, this looks like just a "I just hate Reddit! There's gotta be something I can hit them with!" flailing attempt to me.

They 'allow' people to delete their posts and accounts...

But never actually delete anything from their databases. I've had years-old comments I deleted mysteriously reappear despite being gone for months.

So contact them about that, then. This doesn't change anything. If they were GDPR-compliant before they're still GDPR-compliant, if they weren't GDPR-compliant then they still aren't. My point is that this AI training stuff has nothing to do with that.
Did you read the parts of clear informed use case for any further processing. I asked the people i know still go there none of them where even aware there was anything going on.
Isn’t it enough to remove any connection to any personal identifier before sending it? LLM training doesn’t care about your email, it cares about a certain quality of question/answer pairs, and reddit has a lot of those.
It is not enough, no. The LLM might reveal training data, showing the original text and that is a simple Google search with site:reddit.com away from identifing the user. It's trivial and thus not anonymized.

True, however I assume that Reddit is supplying Google with just the text. So, yes Reddit is collecting lots of PII, but that’s not what is going to Google to deduce it - unless you dox yourself in the text.

Not trying to be deliberately argumentative, just thinking this though, much as I dislike Reddit, the case feels weak

It doesn't matter, as long as the text is supplied as is, a simple Google search with the text and site:reddit.com will reveal the author, keeping it identifiable. True anonymization under GDPR almost does not exist, as it would destroy the dataset and make it unusable.

I deleted my first Reddit account a few years ago. When the whole API fiasco happened and I moved here, I realized that Redacted didn’t finish the job. I tried to get them to remove the rest of my stuff through a GDPR request, but they wouldn’t do shit, and they seemed to think that was acceptable under GDPR. When you delete your account, they (claim to) delete your associated email address, so they also “couldn’t” verify that it was mine.

FWIW, HackerNews has the same policy.

It wi reveal the username, not the identity of the author

It doesn't matter what it tells me. Personal data is clearly defined under GDPR as data that can be used to identify a person. It is irrelevant if you or I can do it with publicly available data, reddit has the data and that is enough to qualify it as such.

A DPA might absolutely disagree with my reading of the situation. I would be surprised, if a DPA considered usernames as non personal identifable information and know of no such ruling.

My view is that Reddit has personally identifiable data but the data that is being licensed to Google, isn't personally identifiable because the username by itself is insufficient to identify a person, without the additional data that Reddit isn't passing over.

But I agree I may well be surprised by a DPA decision.
