It's VERY likely that this is why SEGA has allowed it to continue. They understand that the community thrives on it, and they also still buy their merchandise/products so it currently is a win win. When you have these entitled assholes who begin to try and monotonous on it, the balance sways in favor of the company not making as much profit as it can. And when a company doesn't make maximum profits....the thing killing that has to go. I've also heard someone try and use the whole "WELL PEOPLE CHARGE FOR ART" excuse too. I've also ranted about how it is ALSO ILLEGAL, but the same applies. Sega see's it as keeping fans around, and they could give a shit less about someone making a pound or two off of it. Now, when they make several shiny pennies off of it is when companies get angry.
