The depositors took risks by lending their money to such a risky bank for better returns in lieu of the risk. It doesnt matter whether SVB gave 0% interest. It provided other amenities, services and opportunities instead - things which other banks could not take the risk to do. Now these banks who played by the rules and the rest of the people and businesses who played it safe, will have to foot the bill for the risk that those depositors took. This literally says "If you are big enough you can take any risk to win big and have the public pay for it if you screw it up". That's something not afforded to a small business owner. So people who say that there is one rule for the ultra rich and another rule for the majority, they are right.
Additionally removing the burden of the deposits from SVB will allow it to recover some of its lost asset value. The state took over its liabilities now.
