I went through a period of de-googling a couple of years ago. Swapping browser, mobile os, search engine, storage, maps, music, video purchases, voice assistant and even email service was relatively simple, there are alternatives out there which do the job just as well if not better than what Google offer.
The only exception is YouTube, yea there are individual sites that occasionally offer some of the videos I want (often with a subscription attached), there are some federated systems like NewPipe which have some videos but there is no one offering remotely the quantity or quality of what you can get on YouTube for free.
As the article states, it’s basically a monopoly at this point without a viable alternative.
