There’s a lot of C++ code out there and a lot that interfaces with C.

RAII is one method of cleanup but it doesn’t work in all situations. One that comes to mind is detecting errors in cleanup and passing them to the caller.

So it’s not right to call every library that doesn’t use RAII “bad.” There are other constraints, as well. Part of the strength of C++ is to give you a choice of paradigms.
