I'm pretty sure WebKit also doesn't use exceptions. It's not listed in their style guide but searching the repo I don't find any instances and the repo history shows turning them off.
From my perspective, banning exceptions is the exception (a ha ha); not the rule. I've worked on embedded software that (I expect) didn't support exceptions in the provided compiler, but I don't consider that an explicit ban on exceptions - they simply weren't possible.
