That's reductive argument. Who decides who is worthy enough to hold "humanity's best interests" at heart?

That's a subjective judgement that depends on who, where and when you are. Kipling's vision of "humanity" and its interest is very different that Mao's, which is in turn very different from yours.

Technology makes things more efficient, but doesn't change the act. Getting your head bashed in by a caveman, cut off by a 19th century cavalry sabre wielded by a horseman, or vaporized by an explosive shell has the same end result.

Do you equate the person who whittled the caveman's club, raised the cavalryman's' horse or operated the supply train that transported the shell with Google?

The company making bombs is the same as the company making software to deliver those bombs via drone.

Both are working in service of making it easier for the government to kill people.

If that's the case, the person financing the bombs and war are to blame as well. You can't really get away with avoiding taxes, so you can get a pass on that one. However, you probably own a smartphone that was largely manufactured in China. Buying imported goods enables Chinese oppression much more than introducing a search engine that just maintains the status quo and siphons some money away from China.
