I’m not sure if that’s clear or not from my comments, but I completely agree (and pay for JetBrains editors, amongst other tools).

Though in the case of “fundamental / ecosystem center” tools like code editors which e.g. others will build plugins for I believe there’s immense value in it being open-source.

Thus, I’m rooting for them to find a business model where they get our money without making it non-open-source.
