M$ is a big player in IT. By insisting that “secure booting” must be enabled on all ARMed devices on which M$ will licence “8”, M$ is seeking monopoly on ARM. Any manufacturers of ARMed chips will have to prevent GNU/Linux to boot from those chips if they want to sell to OEMs shipping “8”. The only alternative is to supply two types of chips, doubling inventory costs.
M$ will not do this for x86 systems because there are tons of businesses still running XP and they have a licence permitting them to run on new hardware but on ARM there is no legacy software from M$.
While it is less likely that anyone would want to swap OS on embedded systems, many people want to do that for smart thingies with upgradeable OS such as smart phones and tablets. I expect the world should lay a huge anti-trust suit on M$ sooner rather than later to prevent this action. An injunction would be nice.

M$, we’re watching. You’re not going to get away with this. 8-|
