Nobody "bullied" or "threatened" Sony in any way. (Certainly not any abstract mass consisting of "those people" or any of the other stereotyping labels people are using to compare this to the Danish cartoons situation.) Someone contacted Sony and informed them that something that was unintentionally offensive had slipped into the game because no one noticed it, and Sony responded by dealing with the situation.
Is it fair to blame "Muslims" for this? No. The fact that the Quran is holy to Muslims and its text should not be used outside of a holy context is well-known; this has happened at least four times to different games, and every time it was easily avoidable by simply checking out the material being included before it was used.
Is it fair to blame Media Molecule for this? No. Their game is intended to be a fun, family game that's not political but instead lets different people join together in the joy of creation and play. They're not being "censored"; they're honestly removing content that doesn't fit with the purpose of their game in order to keep the focus on what LBP is really about.
Is it fair to blame Sony for this? Well, maybe: a patch (plus altered repressings of the game) should have been enough to deal with this situation to everyone's satisfaction, so a delay was probably not actually necessary.
Anyway, part of being in a free society is that people are allowed to protest and petition for the change of things they don't like. You can't act to protect creator's rights to express themselves while objecting to critics also expressing themselves. In an ideal situation, one of two things happens:
* Content is released, critics complain, creator decides that the offensive part wasn't actually part of their true creative vision, they change it, everyone's happy.
* Content is released, critics complain, creator decides that the offensive part was part of their true creative vision, sticks to their guns, critics continue to object, nobody's really happy but everyone got to express themselves freely in the marketplace of ideas.
This case is just situation #1, so please stop throwing around words like "bullying" and "censorship."
