Get the support of Cpanel for the fork and it will replace Wordpress. Cpanel powers a significant amount of Wordpress sites, possibly even the majority of them.
We built our own hosting platform that is vendor agnostic, but we’d happily support these larger platform oriented players as a matter of open source collaboration.
In the meantime, I’m looking for an alternative to my journaling app, Day One, which sadly was acquired by Automattic a few years ago and shoved into their mostly languishing “Cosmos” (stuff not WordPress related) team. That’s been a long time coming though. They introduce feature regressions a lot and don’t really “do” feedback.
