Interesting discussion. I have never heard a criticism of "how come," and I hear people use it all the time. It's not wholly interchangeable with "why." "Why" asks for a reason, and "how come" is short for "how did that come to be," or "how did you come to that conclusion" -- it's asking about a process, not just a reason. JME.
First let me say - NONE of what I am about to say is meant to be offensive AT ALL. I would simply like to talk about this and exchange ideas and information. Please don't think I'm being ugly.
No offense taken. As someone who works with language for a living, I find these kinds of conversations really interesting.

I have never heard a criticism of "how come," Really? That is shocking to me. When I went to school, we were NEVER allowed to say it in class under penalty of ..... I dunno....some sort of medieval torture?

I just know that we NEVER EVER EVER said it in the classroom. I ASSUMED ( and we all know what that does) that it was the same way in every school.
Really truly. I have never heard "how come" criticized as incorrect -- not in elementary school, not in community college, not in university, not in graduate school, not working for professionals or professors, not when I edited professional journals or books, not as someone who writes for a living. I have never, ever heard anyone say "how come" is incorrect...until I read this thread.

and I hear people use it all the time. Yes, me too, but I had always thought that they didn't particularly care for English class. I'm not being funny or ugly here.
It's not wholly interchangeable with "why." "Why" asks for a reason, and "how come" is short for "how did that come to be," or "how did you come to that conclusion" -- it's asking about a process, not just a reason. Why not ask "Why did that happen?" instead of "How come that happened?" I have sat and thought about this for a while and I have not thought of a single instance where you could not replace "how come" with "why".
I would really like to hear your thoughts here.
The difference in "why" and "how come" really subtle. It's not as much that it changes the question, but that it anticipates a different answer.
If Mary said, "Jack is a jerk," and Jill said, "Why?" Mary might answer, "I don't know -- maybe his parents are jerks." Asking
why Jack is a jerk is asking for a
reason for his "jerkiness." In other words, here "why" means, What has caused him to be a jerk?
If Mary said, "Jack is a jerk," and Jill said, "How come?" Mary might answer, "I saw him stealing candy from a baby." Asking
how come Jack is a jerk is asking how Mary came to that conclusion or what led up to that statement, rather than what caused Jack to be that way.
Sometimes people just use them interchangeably, which makes defining a distinction more difficult.
I was curious about the whole "why/how come" thing, wondering whether I have been speaking incorrectly my whole life without knowing it. I was not able to find anything saying that "how come" is incorrect. I did find that the use of the phrase confuses a lot of English learners, and that many people asking and answering forum-type questions don't like the way it sounds (the most entertaining question I found: "He replaces 'why' with 'how come' in certain situations that don't sound grammatical to myself.").
I didn't find anything saying "how come" is improper, just that it's informal. I think it's possible that disdain for "how come" may be just a preference without much basis in actual rules (kind of like the distain for ending a sentence in a preposition or starting a sentence with "however," neither of which is improper, but that fact doesn't save them from the loathing of many elementary school teachers).
Grammar Girl says "'how come' is a legitimate substitute for 'why.'"
The Cambridge Dictionary defines it as informal and asking how or why something happened.
The Word Detective doesn't have a problem with it (and notes that his wife has published three books with "How Come?" in the title).
So while it may have been beaten into you as kids to never say "how come," perhaps you should have asked, "How come?"

I'm kinda curious about how it came to be hated by some teachers, but I'm all researched out at the moment.
My least favorite phrase: "10 items or less."
