A monopoly (in my mind) would be more like Comcast. Since they've lobbied for laws in a lot of places that make it extremely hard to dig up the ground and put in new telecomm infrastructure, they completely control the supply of terrestrial internet service and there are literally no other ISP choices in many places. Thus, your only alternatives are non-terrestrial ISPs (LTE, satellite, etc).
I suspect that my increasing dissatisfaction with Google as a search engine may be a byproduct of the arms race against spammers; maybe it doesn't easily find good niche content the way I remember it doing 10 years ago because the signals of 10 years ago are too easily gamed. If that's true, then no new search engine is ever going to be as impressive as Google was when it first arrived. Similar to how no new antibiotic is going to be as impressive as penicillin originally was. The pathogenic elements have evolved too much resistance to permit the same "miracle product" experience again.
