I'm not talking about those providers hosting exit nodes. I'm talking about general web sites and resources hosted by them and the traffic that goes there.

I'm confused. You're worried about people hosting clearnet websites with cloud hosting providers? Or non-exit relays?

Correlation between all kinds of relay traffic and clearnet traffic. Entry traffic would be the worst, allowing end-to-end correlation.

Also remember that the circuit data contains far more information than packet timing, and that it may not be sufficiently secure when on a VM or cloud platform.
