I have a hunch that the chief issue with the cloud is that it enables and promotes easy sprawl of the infrastructure. It's just so easy to "scale" your way out of glaring performance bugs such as unoptimized queries where that becomes the default behaviour of most engineering departments as horizontal scaling is often already baked into the different cloud services. On the other hand, hunting for the root cause of performance issues is a complex, uncertain process especially with the crazy Rube Goldberg contraptions that most cloud solutions tend to mutate into.
