Not well known in the west, but Mitsubishi has been and is active in an insane number of business sectors:

Shipping, motor vehicles, home electronics, bank and finance (UFJ holdings), nuclear power, cameras and optics (Nikon), industrial chemistry, beer brewing (Kirin) and real estate.

That's just the zaibatsu/keiretsu/chaebol system. Samsung also does everything from shopping malls to credit cards to heavy industry.

Google was a search engine that made money via ads then pivoted into an ad platform that also has a search engine. Android and Chrome are about ensuring they have a seat at the table and don't get pushed out by Apple or Microsoft. The first thing of significance they've done that doesn't fit this is their cloud platform.

You could as well have said: That's right, Google's cloud platform is a counterargument.

Their cloud platform is the same thing: trying to not get pushed out by Amazon and Microsoft.

Google Cloud is about ensuring that those two have competition and can't somehow pull an EEE. Extreme scenario: vast majority of world's online businesses are hosted on AWS and Amazon for whatever reason creates their own AWS ad service and forbids or undercuts Google AdWords for everything hosted on AWS.

"EEE"?

Embrace, Extend, Extinguish

This is the first time I've seen it shortened to an acronym.

I'm pretty sure I'm not the first one to turn it into an acronym: https://en.m.wikipedia.org/wiki/EEE :)

Another counter argument: Elon Musk.
