You're right articles are technically better in those ways, but the reality is that people are watching videos more and more. The content that people used to consume via an article is now being consumed via video, and it seems to be preferred.

Between that and the rise of ad blockers, it doesn't surprise me in the slightest that sites are fleeing to video. I think it's actually in their best interest, lest they be left behind and replaced. I've been seeing this a LOT with gaming related content. YouTube channels are essentially replacing game sites.
