This is a concerning aspect of Ethereum's strategy to push scaling to layer-2 networks: Ethereum is a heavily audited and tested protocol that runs an extremely decentralized network of diverse clients. L2s can be...an AWS instance running arbitrary buggy code. Much of the confidence in the "base layer" that people using Ethereum currently experience will be significantly undermined if mundane transactions wend in and out of different L2s.
