Good point. Though if I own an asset that made me over a billion dollars for basically doing nothing, I might consider reinvesting at least some of it...
There's always a lot of disconnect between folks talking about how the world should work and how it does work. Seldom does switching between those modes leading to productive conversations.
Sure, but not necessarily in that asset. Softbank had sufficient money available to invest already before that, they just chose not to; and if it was not worthwhile to invest in expanding ARM before that deal, it most likely was not worthwhile after it failed and they will invest that billion in something they consider more profitable.
