From the article, it doesn't sound _too_ hard to not be a customer of any of the companies (and I was Google-free for a long while until I had to use an Android for work purposes); what is difficult is not interacting with any customers of these companies in addition to not interacting with the companies themselves. This person didn't use Signal, for instance, because it is hosted on AWS. That's like saying you'll stop visiting shops that have Verizon Business internet or similar, which to me seems very different from just trying to cut Verizon out of your life.
