Apple doesn't try to tap markets that doesn't own and to force their own ecosystem into those markets. Google does. That's the fundamental difference.

It is okay for them to do whatever they want with their Nexus/Pixel devices, since they fully own them. But forcing some random DTV vendor to install Google Search, Google Social Network, Google Online Shop, Google Payment System, Google This and Google That, just because the vendor chose to adopt a free operative system into their system, it's just abuse of power and monopoly.

It automatically gives Google an advantage over the Search, Online Shop, Social Network, etc, markets. It is basically impossible to start a new video streaming business in the DTV market, for example, when you know that every single DTV system has Youtube already installed just because Google mandates so. And Youtube is "good enough" for 90% of the people.

The entire world doesn't suddenly owe something to Google just because they made something open source.
