Can't tell if you're trolling or you're just really badly informed. Ah well, here goes:

There is no such thing as a mebibyte.

Wrong. I could quote you a normative reference, but I can't be bothered. In contrast, you cannot quote a normative reference which proves that there is no such thing. Bad luck, try again.

A megabyte is always 1048576 bytes.

Wrong. According to written definition a megabyte is 10^6 bytes. Historical computing usage has it as 2^20 bytes, but it is not wise to insist that that is the only interpretation. Indeed, if you really want to express 2^20 bytes, you are better off using the term mebibyte (MiB) because that is, unambiguously, 2^20 bytes, and can never be anything else.

You also never use megabits when referring to file sizes,

"Never"? That's a bit strong. What if I were storing, say 128-bit MD5 digests? It might make sense to talk about my filesize in term of bits, at least for an intermediate value.

only when referring to the speed of a network connection.

"only"? Again, a bit strong. If you're going to argue, you need to make sure everything you say is 100% factually correct.

A megabit is 1000000 bits but it's rarely seen not per second.

OK, you have something there. Megabits are more commonly used per time interval than on their own.

So what do we have? One out of five? Doesn't really convince me that you have any idea what you are talking about.
