You want to stop me buying something....
...this right here is how you do it:
It would appear forthcoming processors with SDSi may be arbitrarily restricting some features until obtaining a ‘license’ after the fact.
Look, we all know when we're getting screwed. Payment is a social contract just as much as a legal one. You did work, and you deserve to get paid for that work. That's fair. Making me pay for something I already have breaks the contract. I'm clearly not paying for all your hard work, because it's very obvious that it doesn't actually cost you more to give it to me or not - seeing as you have in fact done that, you just expect me to pay again despite having already bought the thing, and despite the hardware in question being right fucking there already.
Car companies keep trying this and it is pissing consumers off. Everyone needs to cut this shit out.
