It boggles my mind that people cannot understand this. Of course time is your to do with as you see fit. If you want to download the ads and bypass them after the content is presented, in the spirit of TiVo, by all means do, but don't selectively choose to download what you want. Instead you should just not visit the site.

Alternatively if you'd like to install an extension (if one were to exist) that warns you that ads are attempting to load before you are given a chance to consume the content and then gives you an option to return to where you came from, that is fine too.

But to deliberately reject the advertising adjacent to content is an act of thievery.
