Whilst I largely disagree with you on advertising generally (see Adam Curtis, Neil Postman and Jerry Mander for the long argument), I have to agree with you on the growing preponderance of low-quality ads.

I see few to none on Firefox, but even with a firewall hosts blocklist, Chrome/Android shows the bottom-feeder stuff on, again, supposedly reputable publishers' sites: TIME, CNN, Salon, Vox, and more. And the only impression it gives me is that thes companies have to be absolutely desperate to let that crap darken their pages.

You're right, it's absolutely insulting. To both the reader and the sites running the spots.
