Of course the main differences being that:

1. Robin Hood stole from the rich and gave to the poor. When was the last time anyone here received free counterfeits from counterfeit manufacturers? Fansubbers create and distribute their works for free and stop fansubbing/distribution once licence is acquired by a company like ADV. I might understand KOers selling their products at a cost that just covers their manufacturing costs, but not making a profit - that's what a lot of fan artists do, like people who make/sell doujinshi. One example was Ichikawa Hirofumi who sold his Cybertron Chronicles comic at BotCon Japan 2000; the price calculated for him to break even and cover his costs... he had no intention of profiting. Takara then stepped in and ordered him to give his comics away for free which generated massive negative fan backlash against Takara because Ichikawa was clearly providing a product made by fans for fans (and also, it was his own original works and not a pirated product). Takara have since made amends by letting Ichikawa work with them on several projects. But as I understand it, KO toys are sold with a profit margin... so unless KO makers reduce the price of their toys so as to reduce their profits to around break even points (as is the case with doujinshi), then I really cannot see how they can take any kind of moral high ground. It puts them in the same boat as Hasbro -- people out to make a profit; and there's nothing necessarily wrong with this... but we do question profiteering when it comes at an unacceptable expense -- in the case of the allegations regarding Hasbro's factory, it's a human expense, in the case of KO makers, it's at the expense of intellectual property. Two wrongs don't make a right.

2. The Sherriff of Nottingham consciously knew and permitted his practices to worsen the lives of the people. So far it doesn't seem apparent that Hasbro were consciously aware that these questionable practices were happening, and to Hasbro's credit, they did say that they will investigate (whereas please for the Sherriff to help people fell on deaf ears).

3. The story of Robin Hood is about an uprising against corrupt authority - much like say the Rebel Alliance or the movements we saw in Tunisia, Egypt and Libya recently. Hasbro may be a big toy corporation... but they're hardly a government. But I understand that corporations do have massive influence over governments... hence the suggestion to #occupyHasbro. If I were a single dude without needing to worry about a family... I'd seriously consider pitching a tent in Epping (or Pawtucket Rhode Island if I lived around there).

Could Hasbro have been more proactive rather than reactive? Absolutely... but it's not like they're ignoring the problem and doing nothing about it.
