That’s actually a really good point. I think, ui wise, skype and slack served a different audience. I think skype was about 1-2-1 messages and calls, whereas Slack was about chatting amongst team members.
Teams as a product feels like a really direct competitor to Slack in a way that Skype could never do (at least in the last iteration I used it in).
As for Teams, same here. In my last job I had slack and it was quite pleasant to use. Now at my new(ish) job and we are all forced to use Teams as part of the license. And I guess that is the reason behind EUs decision right there.
It’s a fork bomb. Specifically it’s a piece of code that recursively calls itself and then it calls itself to run the code.
Thank goodness it did not work, but please do not actually run code like this!! Do your best to figure out what the code is doing before you attempt to run it!
