My complaint with this article isn't about watching the ad or not, its that it autoplays with sound. For example, I didn't see the warning and I played it in work. Luckily nobody heard it because I closed it quickly enough, but, still, auto play is not ok.

Nope. Their revenue model isn't my problem. uBlock Origin enabled for 99.9% of sites I visit.

By doing so I'm basically using a browser unable to render their ads or be in tracked by their advertisers, I don't see anything wrong with that.

I'd understand if they ask not to rehost their content tho.
