Yep. So is eavesdropping on people without telling them and then posting what was said to the Internet. Can't say I'd recommend either, but they both happen with surprising frequency.
The OP overheard this stuff because they were waiting for the conference call issues to get worked out. They couldn't exactly not listen.
All is not lost, though! Maybe OP can go back and apologize for telling people about the racist jokes the Crytek people made at their expense. Wait, no, that's entirely ridiculous.
When people unknowingly do things that upset you, the considerate thing to do is to tell them first, not the whole Internet. Give them a chance to explain, apologize, amend. If they don't to your satisfaction, then by all means go wide.
