"I don't get all the hate for C++"
You don't get it because it is not hate. All programming languages are technical artefacts and should be analysed for what they are good for, where they are a match to some problem domain more than others. But they should also be criticised for their cross-domain flaws.
What computer people should aim for is simplicity. C++ is the antithesis of that. That is not hate on the part of people pointing that out – the problem IS WITH C++.
"If that's not your use case: pick another language. It's as simple as that"
No it's not as 'simple as that'. Many are stuck with having to suffer C++ because of its flaws. Some can see the flaws – others just don't know that is why they are having a hard time programming.
"It is definitely evolving."
Evolving towards what other languages were 30 years ago. Still contracts are put off until C++23. Many people who know other languages roll their eyes and say 'C++ finally got that'. But then they look at it and the C++ way is so much more obscure and then you find it interacts badly with other parts of the language in non-orthogonal ways.
"The right tool for the right job should be the mantra for every programmer." The C and C++ world is full of these false mantras. Yes, there is some truth in that. but in contrast C++ tries to be the tool for all jobs and in that becomes overly complex. The right tools are simple and sophisticated. C++ takes the unsophisticated and complex path.
