Old rant here. Took place ~2 years ago and just remembered it recently:

For some reason our company decided to disable incognito mode in Chrome... Wtf, who comes up with that shit?!
Our team has different certificates to test our application and therefore the private mode comes in quite useful. Otherwise you would need to close and reopen all browser instances again.

At least, after a shitstorm from various teams they unblocked incognito again.
