It's good advice, but I don't think it's sufficient anymore. I'm quickly losing faith in any kind of "vote with your dollars" argument that by not using the app you can pressure the company to provide a functional website. The big players are too big now and they are close to being able to create and control their own customer base rather than having to woo them. I don't see a positive future without radically stricter laws and enforcement (as in, if a company is conditioning any service on tracking, they're fined in the double-digit percentages of gross annual revenue). These bad actors will not change unless they're bludgeoned into doing so.
