I've taken to say Fucking Teams™. Our company has Slack and our client uses Fucking Teams™ and it's a constant meme of audio not working, sharing not working, notifications not working, etc.

I just hate the thing. It's inferior in every way except that it's dirt cheap for the client and it's already there with office suite.

Office suite is another pet peeve of mine when it comes to sharing information. Just make a PDF! Do not share your .docx file. Half of my team don't even have an office suite installed. So we get 3 or 4 different renditions of the same document depending on where we open it in (Libre, Word regular, Word web, Google docs). Just make a god damn PDF!
