I honestly can't believe the author would go so far as to suggest using pi-hole when mv3 becomes forced (ubo will likely continue to work, but Google will be able to collect filter stats, so still best to avoid). Not only is a pi-hole a project, that only works when you're at home (or you're learning more about networking, and it will likely never work right on mobile data), that costs money to set up, DNS blockers are what Google wants you to use, because they serve their ads through the same domains as their content, and if pi-hole ever becomes popular everyone else will too.
The obvious alternative that is much better in all aspects, respects your privacy, and and is literally free, works everywhere and is not vulnerable to same-domain hosting: firefox. Literally just use firefox. Install ubo, even on mobile, and you're done. Any qualms you might have about switching to firefox are either false (firefox is now faster than chrome in lighthouse tests) or Google brainwashing you into thinking your workflows are completely static when you could easily adapt to not having the exact extension you so desperately "need" to work. You don't need it, because you worked fine before the extension, and honestly I'd be surprised if you can't find a ff extension that does the same semantic thing for you.
Suggesting to continue using chrome but with a worse adblocker is nonsense and the author has drank the kool-aid.
