Sure, but when we're talking about a core foundational feature, they do. Richard Stallman would absolutely be willing to say, "We 100% guarantee that gcc will never become non-free software" instead of "we realize that not all gcc users are ready to move to non-free software yet, and we promise that versions 7 and 8 will continue to be free software".

For a lot of people here, not remotely storing the vault is such a core foundational feature.

I did read the blog post you referenced, and that's exactly why I believe they intend to go cloud-only.

Saying something like "we will never force users into cloud storage and sync" when talking about a product like this just isn't that hard, unless that's exactly what you plan to do. Many software vendors have corrected misperceptions when changes seem to point in a direction some users don't want to follow.

This is not a case of misperception. The way they've talked about this make it quite plain that's where they want to go, and the careful phrasing ("at this time", "yet") makes it obvious that they intend to.
