i think the last 4 years of whales doubling, triping, (and in some cast even more) their stake at the expense ofcommunity, not to mention cashing out millions in USD with constant powerdown and selling at expense of steem prices already proofs that very large stake doesn't mean a decision for the betterment of all
besides even if 25%-50% of steemians traffic gets drawn to tron, that is worth close to 10x his ninja stake due to network effect and size of tron, he can benefit a ton with zero Steem price movement even negative, I'm sure you are aware he already have > 1 billion USD funds raised during boom time. The whole steem blockchain could be a tax write off for him, he really wants the power and traffic steem generates...that's the primary value.
