reading it the second time (last time I read it a year ago): - Is ad business model a major reason Google is not providing a platform or hesitant about it? (Out of Amazon/Apple/FB/MS, FB is the only other primarily ad-based company (or is it?) so I wonder how FB is doing it). Because programmatic interfaces means developers can program out ads (unless there's a way for a service provider to avoid that situation, IDK). - Or has Google moved towards platform/accessibility model recently? or is it same old same old?
