True, several sides, 1. It's not bait and switch, you have a preview of the text and if you like continue, its upto platforms which publishes the link to mark it as paid or free - or by crowdsourcing. 2. Just because a model isn't perfect that doesn't justify a illegal or unethical action. If you don't like it, don't consume.

I agree with you on advertisements, I don't like an ad ridden internet either, but I have come around to thinking, the alternative and the incentive to ad free internet is an easier payment access

My concern is less the page itself showing blurb-with-divider, but what happened a second before when someone clicked the link.

Is there a standard way that these sites are up-front about "Most people won't be able to see what I am choosing to reveal to you" which is communicated to search-engines, and the search-engines are at fault for the bait-and-switch?
