Cinavia is a low-level watermarking system, mandatory for certified players, to identify illegal copies.
But I've often seen that argument on various forums. Like e.g. why Popcorn Hour devices after A300 and C300 no longer supported BD-J, but having no problem playing the videos on a Blu-ray. "Cinavia", people said. Same goes for Dune devices.
So I assumed maybe it was a licensing issue. Because being able to play M2TS files doesn't require a license - so any chip can do this without paying The Blu-ray Disc Association anything. But as soon as BD-J is added - then you can't escape that you're playing a Blu-ray - and then you have to pay a license fee to BDA.
And when Cinavia was introduced, it became - as you say - mandatory in all players, and thus upping the license fee (I assume). So avoiding BD-J probably made a lot of sense from a financial point of view.
I don't think it was a decision by Cloud Media (Popcorn Hour), but rather by Sigma who made the chips.
I thought Realtek did the same, but apparently not, if RTD1295 in Zidoo devices is what handles BD-J. I always thought it was software that handled it in these Android TV boxes, just like Kodi v18 will.
