Sure. But not that way. Change of PoW is a last resort and extremely risky option. It's just one step lower than pushing the mutually-assured destruction button. It is more of a deterrent than a practical alternative.

The guy doesn't even hold BTC. No wonder he doesn't fear the consequences of taking that action lightly.

Also, it seems that if he ever had BTC and sold it, he didn't pay his taxes. He doesn't even check the tax report he submits it seems (or he should already know what is and what isn't automatically reported and included).

I still remember the level of stupidity he showed when he asked for the price his donors paid for the BTC donated to him. And when people tried to tell him how wrong he was, he didn't listen.

He is a good coder though.
