I don't think it's fair to blame the SVB depositors for the bank run. Perhaps you can blame public figures (VCs etc) who catalyzed it. Once a run starts, though, it's in your interest to run too.
If you had >250k in SVB and you managed to get it out before it was shut down, you'd be pretty happy with yourself right now. If you run a business and have an obligation to share-holders, it would be negligent not to try this at least.
