... from the worst of all market predators, small businesses.

depending on what exactly you mean by FTL, it's either the same thing as teleportation (instantaneous movement of information) or even stronger (time travel)... given the topic, I just assumed the former

Saying entanglement is like teleportation is basically the same as saying that one-time pad is like PKI. With OTP, you distribute key material 'ahead of time' (just like you distribute parts of an entangled system) and then you can magically 'communicate' (securely in the case of OTP, instantaneously in case of teleportation). This all works only because you distributed things beforehand and then conveniently forgot that part. Even then, entanglement-based 'teleportation' is useless. If you forget fancy lasers and particle pairs, all you need for this kind of 'magic' is a pouch with a black and a white marble. Person A takes one out but does not look. Person B takes the pouch with the remaining marble and moves to Canada. Then A looks at his marble, discovers it is white and instantaneously knows that person B has a black one. Oooh, magic. Not.

The proposed applications are rather incoherent. Claiming that something is 'encrypted' while it is also possible to data-mine is nonsense. A real homomorphic encryption scheme would only allow the owner of the encrypted data (i.e. the party that knows the encryption key) to decrypt the results, definitely not some third party. How these folks make the leap from 'homomorphic encryption' (which they don't even have) to 'secure, privacy-preserving data mining' is less than clear. I call BS.

I think you intended to post this on the first of April not first of March.

Well, his argument is that maybe the "linux is free of charge" (a commonly heard phrase) is a bit pointless, especially in corporate environment? And that actually, you can't save any much on acquisition costs by not purchasing windows. Which is IMO interesting point. So what is your problem?
