Your web devs must suck then dude. I don't know a single web dev who doesn't go out of their way to provide the best range of browser support possible.
I would consider that a contradictory statement. In order to provide the best range of browser support it is usually necessary to not code to web standards to support older browsers (that do not support latest web standards) or to support newer features (vendor specific CSS, etc).
I bet every single one of them let the Presto engine die because they did not test with Opera.
