This article is a misguided attempt to bemoan Panasonic for not enabling Amazon Prime video on their devices, which really has nothing to do with ecosystems and more to do with inferior technology and/or poor pre-purchase research.
I don't view Prime Video as an ecosystem but more as an added value type of thing. Beyond that, it's opt-in, therefore not limiting.
If the OP wanted Prime Video on their TV they should have purchased a TV that offered it, or buy a box that does it as an add-on.
Is that not rather the point of the post? I read it as Panasonic is trying to enforce its own ecosystem. It's not playing well with Amazon's ecosystem. Amazon's ecosystem doesn't play well with Android either (which to me is rather surprising, given Amazon has Kindle on Android)
So he's expecting Panasonic to upgrade the software to support it? I don't see how you can blame Panasonic for not having something that didn't exist when the TV was made.
I'm not a Panasonic fan, but I would guess they a) can't afford to add Prime and/or b) are trying to offer what they can in place of it.
The fact that you have to have some custom client (I don't care how thin it is) to get interop means it is an ecosystem.
There are business reasons to avoid interop (it costs money, it removes branding opportunities, blah blah blah), but let's not pretend they are anything else.
