I've largely cut out Google, but still occassionally use YouTube, Maps (usually through a 3rd party), and very rarely search.
For me, StreetView and the huge library on YouTube are just too useful to completely give up, and, unfortunately, I don't know of any alternatives making headway in those areas.
In fewer cities and increasingly hard to find in the interface (because a lot of it is growing out of date, and it is in general more rare than Street View), Bing Maps also has a really cool best of both worlds "Bird's Eye view" taken from helicopters in daylight at a particular distance and an isometric-esque angle chosen to provide a strong amount of detail. I've found that be extremely useful for picking up a neighborhood-worth of landmarks in a glance for navigating a space by foot or car. It really is a shame Microsoft/Bing stopped advertising it so heavily as a competitive advantage and have let its prominence in the UI disappear to the point where finding it is a labyrinthine task, but unlike the mythical minotaur, I know it still exists (for now).
I don't know what to do about YouTube. I keep hoping that they've made the non-Premium experience so bad that enough of the people I follow might move to better platforms, but so far network effects win again.
Here in Colorado, for example, Bing Maps doesn't cover anything in the western half of the state, not even larger cities along the interstate, like Grand Junction. Meanwhile, Google has Streetview imagery for practically every paved road in the state, and even a lot of forest service roads in the middle of the mountains. I know that's not a big deal for most people, but it's a huge use case for me to help plan bike trips.
And Bing doesn't cover much, if anything, outside of the US.
there are obvious downsides to plastics, google and TV. that excising it completely is extremely difficult if not impossible in the modern world does not diminish the positive effects of reducing consumption.
Also would the advertising industry then be like oil/petrochemical complex?
