For additional content, you can accomplish ad blocking in a number of ways. The ones that immediately spring to mind:
browser extension: most modern browsers have some extension framework available. I've been using ublock origin for a number of years with reasonable results
VPN: some VPNs include ad blocking as a side benefit to their primary function. Nord doesn't seem to block ads on all mobile apps or is at least inconsistent in my experience
Network packet filter/PiHole: this has been on my to-do list for a while. Catches network traffic that looks like ads before it even reaches your device. Most involved and least portable
The only option (other than mitm-ing yourself and stripping ads from the html maybe) for blocking first party ads or spoofed first party ads is ublock origin on firefox
dns filtering can only block domains, ublock does full cosmetic filtering.
Ive been using DNS filtering for years and many sites actually collapse the advert space when it’s not used, and while a plug-in certainly can improve the UI, the DNS blocking also disables the resulting tracking, the network requests still happen with the plugins.
Additionally DNS filtering happens outside of a browser as well, so will block ads in literally every app as well, when setup correctly it’s also device independent.
When I still ran my own PiHole, there where days where as much as 60% of the traffic was adverts and trackers.
DNS filtering also extends to blocking things like malware and spam domains
not to throw more shade at twitch, but they have a strict no gambling policy or atleast no unregulated crypto gambling policy...
but they have ads for gambling sites on their own website before you watch a stream.
Ofc it is. You don't just block ads, you also block trackers and so on. I think of it as a privacy thing no matter what jackarse says that it's piracy.
