That strongly depends on the job. If the company has to follow regulations to meet some security posture, wiping the OS (and all the security tools and configuration set up by IT) to put your own favored OS without matching the security requirements could wind up with you getting fired.
“Rarely” is not zero. This looks like it’s opening a loophole to copying open source code with strong copyleft licenses like the GPL:
Depending on how good your lawyers are, 2 is optional. And bingo! All the OSS code you want without those pesky restrictive licenses.
In fact, I wonder if there’s a way to automate step 2. Some way to analyze an OSS GitHub repo to generate inputs for Copilot that will then regurgitate that same repo.
