I really, REALLY like the idea of Copilot. I think it is a glance at what the future of AI can bring to improve programming. I understand where all the litigation and "uneasiness" is coming from, both from commercial and open-source projects.
I've not installed or used it for the same reason (don't want to use AGPL or GPLd code by accident, and don't want my closed source code to be used accidentally as well), but the thought of Copilot being "killed" due to litigation/copyright/licensing issues is sad.
For me, It's kind of like when MP3 first appeared: Sharing music in Napster or downloading Mp3s from Geocities was just amazing. The idea of having such things at your fingertips. Even though I understood the issue the authors had with the unpaid distribution of their music... still, the idea of "what could be..." made it amazing.
I guess Microsoft could be a bit forward thinking, and implement the "Spotify" model in code: Pay OpenSource developers (whoever owns the repo, or whoever made a commit?) a small amount whenever their code gets used through Copilot.
I'm super excited by how "Copilot" related services will look like in 10 years. And I really really hope that the technology/idea doesn't get killed by litigation.
