I suspect they'd have more revenue if they priced it at $100/user/month.
Right now, there is no competition, and an amateur developer will really benefit from copilot - certainly they will be more productive than a developer that demands just $1000 more annual salary.
Tabnine is a competitor! We have been doing this for 5+ years with more developers than Copilot. Please take a look at the posts and if curious visit https://www.tabnine.com/tabnine-vs-github-copilot
