Flash at least is a known quantity — it is possible to license to port to one's own platform (assuming one can reach agreement with Adobe on licensing terms), as was done for the Nintendo Wii (the port being done by Opera Software). Will the EME plugins (and EME doesn't even have a defined API, unlike NPAPI and PPAPI — so will likely be browser-specific even when they are available) be able to be ported by third parties? An argument such as that can quite probably be made to build a business case against EME for a lot of device manufacturers shipping embedded browsers.
