Us consumers don't want moats. But to understand the investment you need to understand the moat: no sensible investor will throw this much money around without one. If you don't understand what is keeping new players from entering the market, then either you've missed something or we're in bubble territory.
That's why it's interesting to try to pick apart where the moat is.
As a user and a consumer, I don't want them to have a moat. Moat means pseudo-monopoly. That is the exact opposite of what we want.
Only the investors and owners want a moat, to keep others out.
So what they're doing? They're competing. Good.
