A court would probably find your work under this license is functionally the same as public domain, except maybe the part about changing the name means you're keeping rights for a particular branding.

That's pretty good, public domain is like the pure legitimate version of what Stallman was going for anyway.

GitHub might not allow a copywrong license to stay on their site, at least not forever, since it prohibits them from doing so; except a court would actually probably rule against the license and say the code can be used, which is exactly how the copyright system falls apart. Apple uses your code and violates your license and instead of losing a lawsuit against Apple where you got your hopes up about the court not lying, you're like "yeah, courts don't recognize the copywrong license, nothing we can do about it except rebel against the courts and use Apple's proprietary code without their permission too"
