It's an entirely different piece of regulation to the "horror" of the OSA.
It's not hard - you're not allowed to target adverts for children - if Imgur aren't able to agree to that, they are within their rights to decide they don't want to properly safeguard the private information of children and withdraw from the market. That many other providers haven't thrown their toys out of the pram and complied with the law would show they decided if they can't tailor ads to children they wouldn't be able to turn a profit in the UK.
