Nothing changes on VoidZero's commitment to open source. Vite 8 is still set to get Rolldown. I mentioned that also in my talks (e.g. https://youtu.be/fnyK-xXxVKU?t=3027)
Keep in mind that this is a super early preview. It will be source-available when stable.
And it will be free for the community, while companies will have to pay.
