It’s interesting, because if you imagine sites actually using these tags to be maximally compatible with reader mode and other accessibility modes, they’re setting themselves up perfectly to be viewed without ads.

I use reader mode by default in Safari because it’s essentially the ultimate ad blocker: it throws the whole site away and just shows me the article I want to read.

But this is in opposition to what the website owners want, which is to thwart reader mode and stuff as many ads in my way as they can.

It’s possible good accessibility is antithetical to the ad-driven web. It’s no wonder sites don’t bother with it.
