The projects should leave. I don't think they are a critical component of OWASP compared to the educational material provided through their documentation and conferences.
I don't especially love either of those projects, but they're arguably the two most important things OWASP works on outside of the conferences. The Top 10 project can't really leave OWASP (ASVS could).
ZAP is the only other project there that I think is all that important to the identity of OWASP itself, but it should just go find its own sponsorship anyways. People like ZAP, but the industry standard is Burp Suite; Burp is Microsoft Office to ZAP's... LibreOffice? Like all the software freedom stuff aside, if you're a professional, you use Word.
> Honestly, if they can get $5-10M from "somewhere else", I say go for it. Then maybe the Foundation resources can be hyper focused on catering to Chapters and Events.
