Yes. As you say it arguably is actually worse to act this selfishly silently. Thiel didn't cause the losses at SVB, he is astute enough to understand how to be informed to the risks and rewards of acting regarding his money. If he speaks to that wisdom, he's being informative and helpful to his listeners.

I'm trying to be objective here, since my dislike of his political philosophy is pretty extreme.

Wearing the loss would be stupid. His ability to survive the losses isn't really material. If he had custody of other people's money and acted to preserve it, he acted wisely to their needs too. What he did I believe hastened the end for less wise people, with less ability to weather the risk and has downstream consequences which follow a run on a bank, in terms of impact on operating business. Stripe and other payment systems suspending clearing, payroll not happening is going to cause problems at large.

He's no more "wrong" than Pelosi or her husband or many other US senators and representatives are, trading against their heightened sense of awareness of the market. If Pelosi trades on inside information she may actually be worse than Thiel in this case (my belief is she has no prior knowledge which would exceed the insider-trading limits, and is technically not in breach of law even when I think what she does is totally reprehensible and inappropriate for an elected leader)
