Here is an idea.
Just get rid of all the ads and related code and infrastructure. and all the extra calls here and there for tracking and spying.
That would save a shitload of required processing and network traffic.
It would also get rid of a lot of terrible websites with shitty content (AI or human generated) which can only exist because of the ad revenue, saving even more resources.
