We have nothing to worry about since Microsoft helped develop it. It will constantly lockup, crash and produce blue screens of death, BSOD.

It's not about protecting us anymore from a very, very small percentage of bad people. It's about taking away our rights one by one. I do understand in public you have no expectation of privacy and all. But if you combine this with other things that either exist or are yet to come out and it possibly becomes scary.
