Earlier quoted context omitted.
Hang on, what? Refusing to advertise knives which are clearly intended to be used as weapons is 'evil' now is it?
Not sure if you're just trolling, but I'll bite. The government has regulations in place on dangerous weapons, which you are ostensibly free, through the democratic process, to change if they are not to your liking. Google has decided that legal/illegal is not a sufficient criteria, and made up their own rules about how you can use their service, but then only applied those rules to smaller clients. That is the evil…
Edit: To clarify, I've used knives professionally (diving instructor) and recreationally (kite surfer), but I fail to see the non-weapon use for a knife that is small (and therefore concealable) and also opens quickly. Not to mention the window-smashing attachment. [1]
