Verifying license compliance is not "unprofessional", it's literally the opposite. Work in industry long enough and you will be see it's a good thing when people are up front about licenses and pro-active about ensuring it's not misused.
I have been working for 12 years.
You should see those emails before you make such comments. I had only asked them why WASM builds were taken out of the public repository, the dev just assumed I was using Mu and told on me to his secretary!? He then tried explaining himself saying he assumed I was young and lacked experience, respect for licensing. Just like you have done here with your comment yourself!

I don't think Janice was rude.
Mu people were rude, and Janice is making the same baseless assumptions they were making.
