Tablet focused design has ruined the web
Nah; the people who still use the web haven't seen much of anything "ruined". They see the web they've long seen, just with a larger set of web sites each month, and maybe a few new features in their browsers. It's just the suckers that succumb to the vendors' enticements into their Walled Gardens that think things have changed. If they'd install a decent browser (in addition to the crippled browser that came with their tablets), they'd see that the web is chugging along as it always has, some parts of it good and other parts not so good.
The fact that the marketers have pushed their New! Improved! products for small, portable computers doesn't mean that the old products have suddenly lost their capabilities. It just means that some of the customers have been persuaded to switch to other things that may or may not be any better.
The biggest problem with "the web" from a tablet user's viewpoint is all the old sites built by "designers" who haven't yet learned that their sites need to work on whatever screen the visitor has, including the small screens that so many people are carrying around now. The days are past when a site designer could design only for people with screens as big as the fancy one sitting on the designer's desktop. If your site doesn't work on the small screens, you won't attract many of the billion or so people who weren't using the web 5 years ago, but are now.
This isn't the fault of "tablet focused design"; it's a problem caused by designers' contempt for people with such small, cheap and portable equipment. They've been essentially anti-tablet since before tablets even existed. But they're slowly coming around, as they slowly realize how crappy their sites really are, from the viewpoint of most newcomers to the Internet.
(Actually, the web has always worked a lot better if you consciously avoid sites created by "designers". Those built by people with an engineer's concern for usability have always been a lot more useful, and they tend to work pretty well on tablets, phones, etc. The "designers" usually don't think they look pretty. But people continue to use google a lot, for example, despite its blatant lack of "design". Or maybe because of it. ;-)
