No, I consider trying to remain control over software even after selling it an unacceptable attempt, because of the consequences it makes to what it means to have a copy of some software.
Blocking modified versions with bad things added is in my opinion is not enough reason to turn code from freely usable math into a controlled product.
That’s because having a choice between ad version from random guy and adfree version from origin creator, noone is going to choose the mod. And if Louis want to prevent situations like with NewPipe, there is a thing just for that: trademarks.
