No you didn't rebrand RedwoodJS. You just silently abandoned it. The doc is not even be revised for the proclaimed new name. Paying for vendor to be locked-in into well-funded platform should not be considered as a bad choice after all.
redwoodjs.com has a very clear letter of intent on the homepage. Our community forum has a description. Our document has a header that describes this.
I'm not sure that you really appreciate that RedwoodJS is open source, and if you cared as much as you're pointing out to care, then you would have opened a bunch of PR requests to help us out. I'm still open to that, so please why don't you help us?
The clarity was not available before the flashy new website and video for SDK are disclosed. Everything was kept in secret from the community for half a year.
