It's almost criminal that the article does not mention network-wide DNS blocklists as an obvious solution to this problem. I stop nearly 100% of ads in their tracks using the Hagezi ultimate list, and run uBlock on desktop for cosmetic filtering and YouTube.
I should really run some to tests to figure out how much lighter the load on my link is thanks to the filter.
I also manually added some additional domains (mostly fonts by Google and Adobe) to further reduce load and improve privacy.
"…how much lighter the load on my link is thanks to the filter."
Not done any rigorous tests but my experience has been rhat it can be lower than a tenth.
It does indeed work pretty well today, but they have already developed ways to circumvent it. For example, serving ads from the same domain as the main page.
