I see twitter as sort of frustration thing, like hyperloop. With hyperloop - he was frustrated by the way high speed rail was being handled in california, and hyperloop came into being as his cost + engineering sort of optimization. But with hyperloop he wasn't forced to buy it. With twitter he just got in too deep and had to buy it. (though I probably don't know enough about the details of twitter and could be wrong)
