There is nothing about open-source software that says you have to allow people to send you changes (mind you, I’m not saying accept. There’s literally no reason you need to have an accessible email or anything comparable). If anyone can submit changes to open-source software, they can also submit changes to anything else, because what is stopping them?

No, I don’t think I am.
