Could it be that it was coincidence? Do you have a solution for reducing extension malware without removing onBeforeRequest?
I made a plugin for scraping using onBeforeRequest. It's very useful.

Yet you can still inject js right into the page. You just can't stop a page that was going to load from loading. They could have taken away the onBeforeRequest redirect capability and left just the onBeforeRequest cancel capability.
Not sure I've heard of any spyware/malware depending on just that cancel capability.
