Actions Speak Louder
Microsoft will be judged by its actions, and its actions with regard to patents belies its pretty words on interoperability and community. Microsoft has shown -- again by its actions -- that it cannot tolerate *any* competition in the computer software arena. Historically, it has used every weapon at its disposal to destroy every competitor that has dared to "steal" its rightful market share of one hundred percent.
Interestingly enough, it is the actions of predators like Microsoft that demonstrate the danger software patents are to innovation. These actions do not serve to advance the way people get work done, but merely increase the profits of a known monopolist. That the FAT patents are considered valuable IP by Microsoft would be laughable if the current lawsuit didn't threaten the jobs and the livelihood of a company far smaller than the Redmond giant. Make no mistake, TomTom cannot settle the lawsuit. If they do, they break the GPL and cannot use the software. If they lose the lawsuit, they will face massive payments to Microsoft. Either way, they will be out of business.
So, yes, judge Microsoft by their deeds, not their words. But judge them on *all* their deeds, and not just the ones their PR department would like you to focus on.
