It's a nice romantic tune, but we live in a smartphone world that's utterly dominated by that platform... If it's to survive, it needs to draw interest from that crowd, a GNU/Linux phone only won't cut it any more, unfortunately. Comparing HTML5-centric platforms that aren't relying on Android is different.... Ubuntu's not HTML5-centric & isn't relying on a ACL, but it has other tricks up it's sleeve, some which Jolla can't replicate. Actually I may be mistaken, but IIRC Tizen's using OpenACL for Android compatibility, either that or there's a big porting effort.
