What those guys did was immature but let's be honest they weren't trying to cause harm to anybody. They may have been trying to be offensive or not, but even then if something somebody says gets you upset that's on you not them. But what she did was just wrong why try to hurt someone's career because they dared to say something she found offensive not to mention they were not even speaking to her. And for all her efforts at least she got one of them fired, and herself too. Funny how the universe works.
This actually happened to me. I was helping out a customer with some software I had written. I told her to download our latest version from our website and to save it to her desktop. At this time she replied. "Goddamnit, I'm not going to tell you this again! I don't have a desktop computer I have a laptop!". I had to place her on hold while I laughed my ass off.
