I wouldn't underestimate the power of grassroots movements. Telling your friends and family to install uBlock Origin and use Firefox instead of Chrome can work, because it worked before to usurp IE during the IE glory days.
Using firefox doesn't address the fundamental problems of current internet business models and permissive web standards.
Chrome doesn't lock you in to google services. It shapes web standards to advance google's interests and protect it from standards that would interfere with its revenue stream. As Firefox must implement the Chrome spec, it's just along for the ride.
Google has previously tried to neuter uBlock Origin, and they will probably do it again. Using Firefox is a good way to remove the power Google has over the web.
