When @gera2ld "ported" Violentmonkey to Chrome, he obviously used Tampermonkey as a blueprint and even adopted bugs from Tampermonkey's code base, which were later fixed.
That is OK insofar as, in my view, he never copied a line of code, and I occasionally get something back in return.

I am not a native English speaker, but I still feel uncomfortable with the statements above.

• What does "ported" (note the quotes) mean here? Is it indicating "stole" or "copied"?
• When did I adopt bugs from Tampermonkey's code base? I don't even have access to its code base.

I've seen the statements above a few times, not sure if they were from the same guy. But now it comes to the repo of Violentmonkey, making me feel offended.

To make it clear, Violentmonkey was a port (without quotes) of Greasemonkey initially for Opera and Maxthon. Later Opera ditched its own engine so I ported it to Chrome because some users as well as me just could not stand the old-fashioned UI of Tampermonkey. Yes, I tried to use Tampermonkey first to save my effort but failed.

At the start a lot of things break because Chrome works quite differently, so I did a lot of tests to make sure I got the same results in Violentmonkey and Tampermonkey, if that's called a blueprint. Maybe a bug was considered by me as an expected behavior and adopted into Violentmonkey, but I don't know, I am never aware of that. I don't have time to keep an eye on someone else's project when I am working on my own in my spare time. It surprised me when someone said that so definitively.

BTW I actually learned something from the compressed code of Tampermonkey about how to get unsafeWindow (using a bug of Chrome at that time), but IIRC it didn't work soon after that.

This project was fun, and I learned JavaScript through the development of this project. I spent a lot of time on it, and it really frustrates me when someone comes out to say things like that.
