They offer a thing they’re calling an “opt-out.”
The opt-out (a) is only available to companies who are slack customers, not end users, and (b) doesn’t actually opt-out.
When a company account holder tries to opt-out, Slack says their data will still be used to train LLMs, but the results won’t be shared with other companies.
LOL no. That’s not an opt-out. The way to opt-out is to stop using Slack.

It’s not even the training. It’s the extraction of the raw data.
You now store PII, that the clients can’t delete anymore (which in itself is a violation) and then do “something” with it. Whether it’s for AI or word counting doesn’t matter. You store PII that is not under the control of your clients anymore and you store PII without the P whose I could be used to I them having ever been informed.
Also, whether AI training is actually legally anonymization is still up to debate, as far as I know.
Assuming it is PII when you store it. This is a complicated discussion that will absolutely come down to what Slack can defend to a regulator
