This doesn't feel like it will work to me, for a few reasons:
1. A video or survey will take longer than just finding the content elsewhere. The survey is also probably more effort.
2. This breaks the "flow". The odds that I get distracted or just lose interest before the ad/survey is done is pretty high.
3. A lot of the stuff I want to read is more "passing curiosity" than "thing I have a dedicated interest in". The effort and time I'm willing to put into access is low.
The real question for me is whether Offerwall is going to make it harder to get around the paywall than previously. There are a few sites that actually send the full article, they just cover it up with an HTML element. You can still see the full text if you open the request for the content in DevTools.
