This is really disturbing to hear as I've incorporated B2 into a lot of my flow for backups as well as a storage backend for Nextcloud and planned as the object store for some upcoming archival storage products I'm working on.

I know the post is talking about their personal backup product but it's the same company and so if they sneak in a reduction of service like this, as others have already commented, it erodes difficult-to-earn trust.
