I guess rethinking the browser metaphor could help.

Like who tells you that ads couldnt just be displayed on an invisible popup window? Or a second screen?

Those sites generally detect if you dont load certain content. So I guess cosmetic filtering (downloading but not displaying) could already help

Yeah and this useless shit consumes sooo much energy. Like instead of an optimized and load balanced database, this is personal, for every user and query. Insane…
