Though I would agree with the sentiment that the project needs to speed it up to reach a point of greater usability or needs more help in doing so, to remain relevant and be seen as a viable alternative.
Eh? how can it be dead with daily commits? Just because there's not been a release in a while doesn't mean it's dead. They could probably be releasing more often but you can also build it yourself if required. https://github.com/reactos/reactos/commits/master
It is a weird niche. If you want no Linux and no Windows but want to run Windows applications it is for you, or maybe if you need a legacy-compatible system without (hopefully) the same security issues?
Otherwise it is either Windows, or Wine on some flavour of Linux.
There are daily commits to the repo. But in terms of tags in git (or mailing list announcements), there hasn't been a release for a couple years (AFAICT).
They did NOT stop releasing. The are preraring the next release with version number 0.4.15. The changelog of this version will look really huge! There was a delay because of regressions to be fixed
