I'm willing to give Microsoft the benefit of the doubt, but the bar is higher.
At this point I can't tell who is being unreasonable anymore -- this is exactly how cartels work, join/cooperate or face consequences. TomTom paid licensing fees in 2009 -- they lost that fight with Microsoft... When Microsoft joined OIN, did it return the licensing money TomTom paid adjusted for inflation?
Again, I'm capable of looking at this optimistically -- this move is better than the status quo, but it is not enough to budge my skepticism given the damage done over the years by Microsoft.
It seems like Microsoft can do nothing to please you. But this is huge for the OIN and its members.
