And this is different to what Apple, Motorola (now owned by Google who didn't stop the suits when they bought Motorola thus making them trolls by proxy in my book) and every other big tech company this decade has done?
If you want to fix this kind of shit you have to get to the root of the problem which is the patent system is broken and until you fix it this kind of shit will continue. This is like blaming companies who take advantage of the fact that offshoring not only incurs them no monetary penalty but they can often get tax breaks for doing so....the problem is the SYSTEM is broken and encouraging bad behavior therefor the SYSTEM needs to be fixed.
We need to push like hell for a law ending software patents, if you want protections for software copyrights and NOT patents are the logical choice and since you copyright specific works and NOT vague concepts like these shitty software "patents" you could nip this bullshit in the bud. I also personally think we need a law that says concepts required for interoperability (such as file systems and formats) should have to be published under RAND terms so that the user will always have a way to get their stuff on and off a device, but that may be just a personal beef, but no matter how you slice it these kinds of bullshit trolls and lawsuits didn't become a problem until software patents were hoisted on us and THAT is what must be fixed. You stop MSFT and they'll be a dozen more pulling the same shit waiting for their shot.
Oh and on a final note, lets get something clear: Linux and Android by extension DOES infringe on MSFT patents, how do I know? Have you seen how many patents have been filed on software since the shitty ruling that allowed software patents? EVERYBODY is infringing! Hell the whole history of computers has been standing on the shoulders of giants so frankly with as vague as these patents are you can't build shit to do with a computer that doesn't infringe! Hell I wouldn't be surprised if every possible way to build a file system or make an audio/video format isn't covered by some vague as hell "method to store files on things" style patent, the whole thing is so broken you are tap dancing in a minefield.
Is what MSFT doing shitty? yep, no doubt, but if we focus on that instead of the conditions that have ALLOWED them to behave shitty all we will be doing is playing whack a mole until the end of time. To use the famed /. car analogy if your front end is shot and eating tires you can change tire brands a billion times, the tires are still gonna keep getting eaten until you get off your ass and fix the front end. Until we fix the patents system this kind of shit is only gonna get worse.
