Slack seem to be doing this to a wide range of groups. The Kubernetes project and CNCF were told by Slack that they would lose access to the paid version with quite short notice.
In their case the change was reverted (I think it caught the eye of someone sufficiently senior at Salesforce), but if you're running a non-profit on Slack and not paying full price, I'd strongly recommend looking at alternatives...
I've never understood why a part of our community goes with this walled garden to host their chat. We're literally an open data project
Edit: fwiw, I know that moving communities is extremely hard, not to say impossible to achieve completely intact, but those who care could choose to join two chat systems. Eventually, the one people gravitate towards will win. E.g. I'm still in the Telegram chats and use those on occasion (also because, as a moderator, I get regular pings), but primarily share content on Signal or Matrix
> UPDATE: We’ve received notice from Salesforce that our Slack workspace WILL NOT BE DOWNGRADED on June 20th. Stand by for more details, but for now, there is no urgency to back up private channels or direct messages.

Is the concept of "full price" well-defined in this kind of situation?
I assumed price was always a matter of negotiation for enterprise-y sales. I'd think a "full price" would just be an attempt at anchoring by the vendor.
