If you don't want to look at what people write you can't say that they haven't written about it.

I don’t think people complain about the internals of git itself as much as the complexity of all the operations.

If you want to read about complaints, you really don't have to look further than the myriad of git GUIs, TUIs and otherwise alternative/simplified interfaces.
