Sure---that's sharing with your friends and neighbors, and that's a fundamental freedom.

But many/most will follow the project directly. You can offer the source code to build yourself , or provide a convenient binary/installer for those who either don't want to or can't (for example).

This is especially prevalent for mobile OS's, where building is an unfamiliar task or PITA for many, even hackers.

Would I personally? No. But I respect that decision.

Your inability to figure out a competent business model that also respects the rights of users is not the user's problem. You have no right to lock someone's computer down, to prevent them from using the copy of the software that you sold them, and the only way to guarantee that is to require the source to be open.

Look, it probably won't matter anyway. Probably nobody is going to use your software.

The same is true of literally every piece of software ever distributed regardless of license.
