Oh, ok, now I'm curious to try it despite EULA (although these days the wide choice of (neo)vim distributions utilizing LSP makes their offering less appealing).
Thanks for the clarification.
The site doesn't stress the not-electron part enough, maybe that contributed to the failure.
Should've probably mentioned it before but it actually used a dual-license model by having an MIT version that lagged behind upstream for 18 months (could be found in oni2-mit repo). During last month when development stopped it was fully re-licensed under MIT (hence oni2-mit repo no longer exists).
