On the home page:
In the companies using C2, appmobi is listed, however I think since it has been bought by intel, intel should be at this place then, but I am not sure about that.
On the C2 specific features page:
"You can also reach the popular iOS and Android app stores using wrappers like CocoonJS, appMobi and PhoneGap â€” all three with built-in support."
I think appmobi name's changed to intel AGI, ejecta and crosswalk are not directly listed, and CocoonJS and Indirectly intel AGI is described "with built in support", but since they were deprecated and the only viable and up to date cocoonJS plugin is not inside C2, the mention of them should not be there anymore (the related screenshot could be updated to not feature cocoonJS and intel AGI too)
If I see somethign else that could benefit for a slight update, I will add it to this ^^
