We're not talking about whether the CTA button should be light blue or dark blue. We're talking about decision to unleash some of the worst garbage Internet has on unsuspecting and unwilling people. It hurts individuals, and drags down both the industry and the society at large. Someone in the company should be able to say "no" to that.
The author of the article described some of the consequences, strongly implying but stopping short of saying one thing out loud, so I'll say it here: chumboxes are unethical products, and showing chumboxes is unethical behaviour too.
(But yeah, I do understand competitive pressure. That's why I hope we eventually get around to killing Taboola and friends through regulatory means.)
