Company G) Companies M software has a bug, we've told them, they didn't do anything about it, we will tell everyone else. (including the punters).
Company M) Oh!, you're going to play it like that are you? OK, this is the bug we told you about sometime back and you didn't do anything about it. Finger is now hovering over the 'enter' key. Not backing down? ok!, it's pressed.

Company G) Ok, point taken. But what if we pool our efforts, (because you and us have common ground now), we can go after that Company A - mainly because they are smug and can be quite lackadaisical.
Win win for the consumer.
