I'm really sorry to hear you had this experience :( I'm not sure who you spoke with, but this perspective definitely isn't representative of the team and/or how I'd ever want to see us talk with developers.

I'm actually a PM for both Live Share, Codespaces, and some of our education-related experiences (e.g. the GitHub Classroom extension for VS Code). A web client for collaboration, with zero-install/onboarding, has always been our north star, and so your intuition/feedback was 100% right back in 2018.

Now that we have Codespaces, vscode.dev/github.dev, and Live Share support for the web, we're actually looking to further optimize our support for education, since we believe we have a lot to offer. In fact, I'd love to connect and hear your thoughts, to make sure we're going in the right direction. If you'd be interested in letting me make up for that terrible conversation in 2018, you can reach me at joncart@microsoft.com. Thanks for sharing this feedback, and letting us know where we can do better.
