If you don't care about those authors, or don't care about copyright in general, or you agree with Microsoft's sketchy reasoning that copyright violation never occurs in Github Copilot (even though Github Copilot is perfectly capable of regurgitating big verbatim chunks of code from its training corpus)... then you won't get the hate.
Not even the FSF had made that claim yet.
They are still in research mode:

The latest conclusions so far:

"Copilot and its developer-customers likely do not infringe developers’ copyrights."
Convincing a court to make a judgement of infringement is not an easy threshold to cross. But Github Copilot, like many AIs, is less judicious than humans about not reproducing its inspirations verbatim: https://twitter.com/mitsuhiko/status/1410886329924194309
If GPL code had a function like `int add_1(int x) { return x + 1; }` and you copy and pasted it, is that really stealing?
What about if you wrote identical code without having looked at the GPL code?
Or even if you've seen the GPL code but type it from memory?
Or if you copy from someone that illegally copied the GPL code?
It seems very non trivial with small functions like this, which is exactly the kind of code copilot outputs anyways. It's not like you're stealing large and unique parts of the code.
