I've done a fair bit of PR writing myself so I'm happy to be skeptical and understand the line between marketing speak and reality.

The problem here is the audience is clearly the developer community (which I'm also a part of). Developer communities have a right be skeptical about key acquisitions of their open source dependancies. It can have massive commercial implications on software design decisions, etc.

Open source is built on trust. Dubious communication does nothing but erode that trust.
