Fine. But the point is the WSJ should be looking at improving their site instead of using google's offering here. It's laziness otherwise.
That's why I think statements like your original comment are unhelpfully reductionist, and my paraphrasing of them was not misleading.
That is impossible. AMP is just forcing some changes and using better tech architecture for the rest. There are already slow AMP pages because of all the re-added plugins, trackers, media and ads.
Other sites could easily work on better tech delivery to improve performance without AMP, which now only decreases the amount of resources/time they have to work on their own site.
Wait, what!? They have EVERY incentive to make sure they provide a quality product.
