Only sort of related, but one time some of the YouTube engineering team made a code change to kill off usage of Internet Explorer 6 by bypassing the usual code screening process to circumvent management. Their boss reprimanded them but eventually got in on it, without going through the appropriate channels. Then the Docs team saw the banner they showed YouTube users, thought they had actually received approval from management and used it as evidence to convince their managers to implement their own banner (who would have normally refused).

All they received was a small rebuke. In fact, management praised the team for the end result of decimating IE6 usage, as intended.

Then one of the architects of the scheme blogged about it in retrospect years later.
