Oh hell yes they could sue, and they’d win too. In countries that have similar copyright laws to that of the US, they’d sue the legal entity (non profit, LLC, whatever) behind the software for copyright and/or trademark infringement, and I’d they couldn’t sue said entity for some reason, they’d pierce the corporate veil and go after individuals. If they weren’t able to ID who’s behind it, they’d sue to block access to the entire work wherever it’s hosted. Basically it would be tested just like piracy is already. Which is sad, because what you’re describing is something I’d very much be interested in. You could try to make it “pretty close”, without copying or emulating any logos, and while that’s not certain to protect against the aforementioned claims, it’s at least more defensible than a straight up copy. How much more? Depends on a whole lot of factors…
