Well put. Concise.

I will quibble though on the "now we can slow down and optimize them" part.

What's happening in practice is that those startups who "lucked" into successes playing the risky-but-many game of mobile & internet technology... those startups now focus on defending their "moats" and optimising their revenue streams.

Hey quibbler, you defend a castle (not a moat).

[netcan]

In the spirit of quibbling:

Moat: from Medieval Latin mota: “a mound, hill, a hill on which a castle is built, castle, embankment, turf”

In the spirit of mixed metaphors: </checkmate>

business catchphrase for the 20s: stock your hill with crocodiles

I was wondering what the heck dictionary you found that definition in, but then I realized you're conflating the etymology with the definition.
