Oh I didn't understand that the question was meant for those of us that didn't make the statement. But I'll entertain it:

Who are these powerful entities that will not understand it but yet have the ability to use it?

I don't believe this. What I think is that there are powerful entities that play a long game, where short-term crises can be anticipated and even prevented, and long-term gains positioned accordingly. Also, no point in stealing coins that will go to 0, so you'd do one or a couple big-but-not-"patoshi" utxo(s) per week.

Bottom line, I don't think that trusting Google, IBM or Microsoft is a good solution to a threat. Also, these can be infiltrated / hacked.
