I really dislike these AI middleman plans. The value-add that Microsoft brings to Github Copilot is near zero compared to directly buying from Anthropic or OpenAI, where 99% of the value is being delivered from. I don't understand why anyone would want to deal with Microsoft as a vendor if they don't have to. The short period of discounted usage was always the obvious rug pull.
For direct instance: Anthropic's Claude Code, despite being primarily written in Python, didn't even properly support Windows until far too recently (suggesting people use WSL instead) and even now is not a great Windows experience (requiring git bash, illuminating that among other things Claude's models themselves haven't trained enough on PowerShell, and I try to avoid Claude's models when working on PowerShell scripts still, personally).
Meanwhile VS Code works everywhere I want it to, out of the box, and VS Code's GitHub Copilot integration does the same.
Also, your "near zero" value add includes engineers at Microsoft/Github following the "which is the smartest/most practical model" meta-game for you and just silently updating defaults in Copilot for you without needing to make conscious choices. Sure, you can follow that meta yourself by watching HN every day and sampling hundreds or thousands of opinions across dozens to hundreds of stories each day, then play a "Netflix subscription game" of switching subscriptions every X months when the meta-game shifts or you can pay Microsoft to do all that research for you (which true also includes their professional business relationships/contracts with OpenAI and Anthropic, which is as much of a feature as a bug in my opinion because it's also a signal in the opinion war noise of choosing the "smartest model [for you, right now]" and does show up as its own HN stories for meta-debate). At least to me that's much more than a 0% or 1% value add, but maybe that's also because I don't trust either Anthropic or OpenAI directly, I sort of don't trust HN's comments as a strong guide to playing the meta-game, it's not a meta-game I want to play, and I'm happy to pay someone else to play it for me.
