I'm guessing the bundling of OS4.1 with an emulated system would a) give a very poor user experience so potentially damage the reputation of 4.1 and b) impact sales of their main hardware partners.
The bundling could be seen by consumers as official endorsement and 'if it's bundled it must work well'. Of course, the experience will be poor - Jonny Consumer may then decide OS4.1 isn't for him so decide against that Sam 460 order.
These companies are supporting a very niche market already. Slating them for trying to protect their reputation, products or partners is a little harsh.
