To answer your question, "we" meant those nations that have been sucked into going down the all-purpose, single-type route.
Sucked into? By whom? Their politicians who refuse to properly fund defense? If all you can afford to buy is one type, then an all purpose type is probably your best solution. Certainly, that's true in the case of the Royal Navy who for decades relied on the Harrier as its sole jet and then (sadly) on no jet at all.
