If file sharring is wrong why does the IRC protocols support it?

Well I'll ignore the part about IRC supporting filesharing since many people have already tackled that point, but I will just say that filesharing is not wrong. The sharing of copyrighted material is illegal in many countries, but that's not the same as filesharing. Granted many idiots use filesharing solely for that purpose but that doesn't mean it's the only one. Another point to make is that many IRC chatters (myself included) do consider using IRC for filesharing to be wrong, in the sense that not only is it a poor substitute for a real filesharing protocol and network but it also often greatly irritates chatters by causing many IRC-illiterate people to come on IRC and related forums such as this one and ask questions about filesharing without even realising IRC's true intended purpose.

Spelling mistakes, grammatical errors, and stupid comments are intentional.
