Hashes of keys were posted, not the actual keys itself.
Team fail0verflow explained how the metldr key could be decrypted just like they did with the lvl2 key which allowed them to run homebrew.
Anyway, the thread seems to go a little off topic by all this hot new psp/ps3 key news. Perhaps create a new topic for it?
GM's methods for creating their psp runtime is certainly questionable. And their probably not the only ones in the scene using this method. However in the end they bought the official devkit and acquired their license for publishing software on the platform. It's not like they're bypassing sony and started publishing directly on the psp, because that would certainly be wrong.
I don't really get the point of this thread, I think it's perfectly normal that the company wants to protect their users by making sure that decompiler doesn't get out. As for the psp, what the they did is legal, I thought it was pretty obvious. They wouldn't be so dumb to license a sony devkit and announce a psp port before if they were doing something illegal. In addition I don't see how clickteam would win anything if all your assumptions were true.
I'm pretty sure clickteam wish they had half yoyo games's userbase, and while I'm no game maker user I applaud their decision to release their product for free and make it available to everyone while clickteam doesn't. And whether or not yoyo games's contact with the community is worse than clickteam's is questionable. Also, if by "making dreams come true" you mean make games, then game maker does that too, without you having to pay for it.
