This, a thousands times. For both Taboola and Outbrain it's clickbaity trash - usually misleading and low quality content. They're designed to "disrupt" so that people click on them and have in the past featured on blatantly false news stories. I'd honestly be ashamed to work at one of these sort of organisations and it further underlines how awful the web experience can be if you're not using an ad blocker.
It's no surprise to me that AMP is popular among users if news sites are not including such garbage in their AMP renditions.
