Totally agree. If the service you're providing is so important, build your system so it can fly on one engine or at least land safely. Multi-cloud is the equivalence of trying to transfer all of your passengers to a different aircraft mid-air.
Multi-cloud should only be for mission critical infrastructure. Very little infrastructure is mission critical. Most other use cases can be temporarily wallpapered over with an "Under maintenance" page unless there's a good reason otherwise.
Multi-cloud introduces more risk than it prevents. Which is why things like simulated failovers and BCP testing is constantly required.
