First off, the author sets up a bunch of straw men to bash down in favor of his point, the most frustrating of which is:
> I watch truly quality TV shows. There are definitely the odd few of those but, if you must, download them and watch them on your computer: without ads and over a short period. At least in this instance you know what you’re subjecting yourself to and you will be doing it for entertainment: not in the background.
This is identical to me making a blog post saying: "Sell all your books: you're better off without them. Sure, you might miss out on some quality literature, but you can always just download them in pdf format and read them on your laptop."
Television is a medium. Every medium has its Two and a Half Men, and the luxury of the modern TV industry is that we have more freedom than ever to pursue programming we prefer. Making a big deal from divorcing yourself from a medium is fine -- of course you're going to have more free time, if I quit listening to music I'd probably have more free time as well -- but doing so with the caveat of 'oh, download some specific shows that you like' is shallow and unfair to the reader.
