Just like how I don't try to run the latest edition of Flight Simulator on my 4-GB, GPU-less device; I also don't try to visit websites built with latest web features using browsers that are clearly not trying to support those features.
NYT doesn't have to hinder its innovative efforts to create informative content just because of a couple of folks who refuse to admit that tech evolves over time.
I understand that ads can be annoying, and for that I use ad blockers where necessary; but for everything else, I appreciate the advancements in the web tech capabilities that enable the creation of amazing stuff.
Well, tbf, I'm speculating based on the evidence provided. But, if NYT provides a poor—or non-existent—experience to anyone, for example, without JavaScript enabled, then it fits my definition of "bad".
JS and ad bloat made HTML5 video and audio tags rendered null with no actual usage IRL.
