Or as Bjarne Stroustrup worded it, "There are only two kinds of languages: the ones people complain about and the ones nobody uses"

And in fact very detailed criticism can be a good indication that the person is not some beginner frustrated with "that bad feature" but a developer who cares a lot about the technology but is also realistic about the things that aren't as good as they could be.

It has some truth but it brushes away any attempt at criticizing the C++ language and completely ignore that different languages have different level of satisfaction.
