They could have settled down, collected their thoughts.

This “rant” literally provides evidence the poster is a crappy communicator. Are we sure they’re not blaming everyone else out of frustration with their own shortcomings?

I suggest they read some Camus and consider in a relative world not everyone is composed of the same statefulness they are.

Ranting isn't inherently bad or good communication, whether or not you like the rant. I believe the thing the op is talking about is really incompetent communication that you see all the time in tech e.g., far worse than you're thinking you see here.
