Respectfully, it's not. Choosing a bank is an aspect of risk management, the act of throwing all your money into whatever thing that calls itself a bank and is most convenient is not risk management, it's risky behavior.
Risk management would be asking the question "should I be putting all my eggs in a basket that seems very tied to the tech economy / northern California real estate market / low interest rates?". Diversification would be trying to get the money you use to pay your tech workers invested in something as far away from tech as possible.
