It's less the specifics and more the trend. Google's direction is, as stated elsewhere, to be seen as the
source of information - not a route to it. As you note, they're incentivising structured content - which means they can appropriate it and present directly rather than providing a link to the originator.
No doubt some will find it helpful (as with AMP). Some will find it unacceptable appropriation. I'm most definitely in the latter camp. I don't use Google search anymore, having transitioned to DDG 2+ years ago. I rarely find situations where reverting to Google is necessary, and when I do, a `g!` in DDG is as close as I get.
I realise I may be in a minority, but as far as I'm concerned both Google and Facebook have jumped the shark. They're become corporate behemoths, a malaise that seems to come to all companies of a certain age and scale. They've lost focus on providing useful, innovative services for real people. Instead, they're all about "shareholder value". Both are ripe for disruption.
