CF disabled the problematic feature within hours, on a Friday evening. After that, figuring out what private data was stuck in search engine caches was obviously going to take some time. It seems clear enough that they were working as fast as they could. Tavis is awesome but I think he was being unfairly hard on them in the project zero thread.

(Note: All of the above is based on my external observations, as I was not yet an employee nor did I have any internal access at the time.)
