Facebook is currently ahead, but I wonder how much of that is perception. There is a lot of media about how Facebook is evil, but that is mostly from a pretty small circle of media and political people, that Facebook is naturally in opposition to. Facebook also owns instagram and whatsapp as well. But everyone over 30 I know uses Facebook, heavily. Instagram is also used very heavily. Amazon has threats from other E-commerce sites, lots of bad press, Governmental attacks, and unionization. Google prints money on search and I don't see enough people swapping to Duckduckgo to bring them down.
Amazon is also kept up by AWS, which who knows if one day that is spun off.
>But everyone over 30 I know uses Facebook, heavily
everyone over 30 i know are past facebook and realize Instagram is adware/spyware.
But about the factory itself, American Factory was quite interesting[1]. Chinese company, but similar culture clash.
It is interesting however that from what I have seen Europeans that wouldn't lift a finger on a weekend would expect Taiwanese to have results on Monday morning, when they themselves only send information about their requests on Friday end of day. So in the middle of the Friday night for the Taiwanese.
