Wrong - Vite is not open core, Vite+ is. This differentiation is important because even if a feature benefits Vite+, if it needs to be shipped via Vite then it has to be open source.
Companies willing to pay for Vite+ help sustain and improve the open source parts powering it, including Vite. Even if you only use Vite and not Vite+, you’d benefit from the success of Vite+, not the other way around.
I don’t really find anything inherently wrong with your definition of “rugpull”. If some people in the community are happy to pay for it and the rest also benefit because of it, that’s a win-win in my book.
