I have heard this viewpoint before from others and I agree about the DNA aspect. The difference, I think, is that none of those companies were involved in a situation that comes close to the threat from a vplm with patents that are really all that. In other words what I'm saying is there was nowhere near the threat level when you start crunching the numbers and digesting all the effects of what an infringer faces from a vplm. The difference are gargantuan, I think. That's why I keep asking what are the potential damages and negatives to their businesses the big dogs will have to suffer when their number comes up. The longer they (Apple or any if them) wait, the larger & closer the threat becomes, but it's a much larger threat then posed in other historical cases. There is no comparison.
