Everyone hating on vscode because it's maintained by Microsoft... Vscode is an amazing IDE with amazing extensions, and the core part of it is FOSS. I use vscodium and connect to the real marketplace, guess what, it works. Does it break some license, sure, but it works.
I'll wait for Microsoft to send me court order, until then, I'll happily use copilot and a bunch of other extensions with vscodium.
Worried about extensions calling home with telemetry?
Block those calls on your dns.
Worried about some extensions that only work in vscode?
Wait for someone to reverse engineer them and pirate them, or wait until someone does a FOSS version of them, or do it yourself. Those last two point is how open source works.
So I think people just found another thing to complain about without any serious arguments. Vscodium is FOSS, telemetry stripped out with alternative FOSS extensions and a possibility to fallback to non open source extensions. It's great because it works and does not completely lock you out.
Sure you have to break Microsoft licenses when you try to install one of their closed source extensions, but as I said above. I'll be patiently waiting for Microsoft to put me in court.
If this is their plan for the extinguish phase, my god does Microsoft have a thing or two coming their way. They made it way too easy for the average dev to just do what they want this time.
