This is quite a reach. VSCode is open source. Some popular extensions are not. Neither extension used as examples here are ones that I use, so they certainly aren’t critical to the product functionality. The argument here feels akin to saying Linux is open source, but some applications available for Linux aren’t, so Linux is thus somehow not actually open source.
