These sorts of incidents would be far more common if bosses shit talked their employees in the public and tanked their brand image in the process in front of their users and future employees. Fortunately, almost everyone else is smart enough to know that it's bad.
Sir, he was shit talking the app (which everybody agrees blows ass) and the dev took to Twitter to whining instead of using the internal platform. Next time your boss admits your product is trash, try shit talking a rebuttal to him on Twitter, I dare you. Elon is his father.
I'm sure the job market yearns to hire yet another Android "engineer" and one who shit talks their boss on Twitter to boot. The bratty stepchild will be fine.
