But how much do you think the average consumer cares about that (or is even smart enough to think about it)? Sure, we all understand the ecosystems because we're developers and we follow that sort of thing, but I'm not sure that the average consumer would see it the same way. If anything, they might be swayed by the whole "Oh, that will work with my iTunes account!" factor.
Netflix's independence is potentially a big deal. In a rational world, the content producers would see Netflix's platform agnosticism as a big selling point. No producers want (or at least should want) their hit TV series or movie to be viewable only on iOS devices or Android devices or Windows devices.
If the price is right, producers couldn't care less about platform lock. If Google, Apple, Amazon or anybody else is willing to pay the right number of dollars, they can throw the bits into /dev/null for all Hollywood cares.
I don't know about that. Nothing like a major motion picture or TV series has ever been platform-locked, has it? Video games, yes, but not traditional "mainstream" entertainment.
