I have some code I know is bad practice. And I only want to know why it is bad practice. So I can justify changing it to my non-tech boss.
Is Code Review a good place to ask?
We only review code from an author or maintainer of the code to avoid legal, moral and practical problem. For your case, since the code is not yours (the company you work for owns it) your question would be off-topic to avoid legal problems.
