Somebody's funding them...
1) There has not been any naming of John Does in any of the recent rulings. If there is no identification, legally they dont exist.
2) People have demonstrated that they can run businesses the size of Psystar with similar staff and similar finances with nothing but their credit cards and bank loans. The only thing that Psystar has that these guys dont is the lack of intelligence on their methods, bad lawyers to defend them (practically no payment upfront) and their arrogance toward the law, Those things require no money much less backers
Even if we do argue the possibility, we can eliminate Dell - they would have backed off the minute Psystar presented their utterly stupid legal strategy that any IP or copyright expert (much less anybody with a smattering of a legal degree) would know was folly. Second, Dell has gone on the record of selling Macs - only with the explicit blessing of Apple. That would predicate them from supporting a company that would do just the opposite - especially when a company like Dell knows that they could be named as an accessory - one that unlike Psystar - they could face big fines.
Microsoft would be the last group of people to sponsor these Jerks. The idea is ridiculous on its face:
1) Why would they want competition in the market by loosing their hardware partners?
2) Microsofts entire business strategy is based on software licenses and their ability to dictate their terms to businesses and individuals. Were Pystar to win, that business model would cripple MSs ability to license their software.
In other words, they would be shooting themselves in the foot.
We do know that they tried to get venture funding by claiming that they would sell millions of systems - but there is no evidence that anybody bought that sales pitch for a minute.
Unfortunately, unless anybody comes out, which is unlikely to happen given the summary judgement and settlement only named Psystar and nobody else and the minute that the appeals fail its finalized, we have to assume that they fund themselves like any entrepreneur does. The idea of mysterious backers is fun to speculate on, like any good conspiracy, those pesky lacks of evidence make it something that we have to reject until we have names.
I can claim John Does guilt in any number of things real or imagined, but without names or any proof of their actual existence, you cannot take such claims seriously. Thats why they are so common in lawsuits - you cast a big net should you get lucky and its easy to do.
