Just toggle the telemetry setting. That’s all

Sure. But functionally wise it’s the exact same software after you toggle said setting. I like FOSS but in this case it has zero benefit.

Alternatively you can deactivate all tracking in VSCode and therefore make it exactly the same as VSCodium afaik. Only takes a few seconds.

VSCodium uses another marketplace. A lot of addons are either on an older version or not even available. Tried it once but moved back to VSCode after a few minutes. I prefer my addons.

Well not exactly the same. I’m not sure anymore but I think it misses the possibility to sync settings via Microsoft account and possibly via GitHub account as well since it belongs to MS but I’m not sure.
