I could check using a proxy or by inspecting the source (it’s just JavaScript) but I don’t actually care about it that much to bother and I think we would have heard something if the switches were bogus, given that VSCode telemetry is such a contentious issue. That’s why I asked if there was other telemetry without a switch, because Windows is like that.
VSCode does not work at all for me without the "Remote SSH" extension. And the "Remote SSH" extension is proprietary and DRM-ed to be not work with the open source code.
I don't see how I'm stretching what "open core" means. This is just like any other open core stuff.
"Paid for" part, yeah you are right. I thought the orange site all agree I paid for Gmail, just not with money, but turns out I'm wrong.
