While I'm not _happy_ about the messaging changes, those alone are not enough to do more than start paying closer attention. I highly, highly doubt that vault export would be the first meaningful feature change, and so I think there will be stronger signals of actual issues before then.

As I understand it, so far the only actual change is an announced increase in prices. Obviously, from the consumer perspective, cheaper is better, but this is a product where I think that a subscription plan makes sense (and the free tier, for now, still exists), and so I'm not going to get mad about price changes. Competitors exist and one doesn't think the new price is worth it, then switch to one of them (using the very-much-still-available vault export).

I don't think the warning is crazy or anything, but in my personal opinion it's a little stronger/earlier than is warranted and the current appropriate response is careful watching.
