If they don't want google to display a snippet, then they can "Use the nosnippet meta tag to prevent Google from displaying a snippet for your page in Search results, or use the max-snippet:[number] meta tag to specify the maximum length for your result snippets. You can also prevent certain parts of the page text content from being shown in a snippet by using data-nosnippet". [0]

That’s playing Google’s game. Where today you “simply” have to do X, which tomorrow will be X plus Y but not Z, and so on. What about Google don’t stealing content by default unless I add a meta tag named yes-google-steal-my-content?

I saw the earliest reference to "nosnippet" in 2007, 13 years ago. Those things are not changing that fast at all.

Did Google change how they do this recently? Because I'm not seeing what you describe. All I see is a headline and an image without any snippet at all.
