I wish people wouldn't abuse the author of that project over this. Giving them the benefit of the doubt in that this was a mistake and not intentionally malicious, it feels really bad for hundreds if not thousands of people to send hate, insults, abuse to a single individual. Shame on the people who are doing that.
The only way you can consider this a mistake is by not having read the github comments here: https://github.com/notepad-plus-plus/notepad-plus-plus/issue...
I think you need to do a little more research before you give the poor, poor little author of 'that project' a pass.
