“Nothing is good unless you play with it.” -George Clinton
It was very exciting for me to ‘break’ the commercial model and take a step away from Google/Apple on my own. This feeling was and still is a significant motivator in my privacy journey in general. This is why I think it is helpful for mainstream users to tinker with cheap or unused second hand equipment first, because doing this opens all kinds of doors to better practices.
The model that PG proposes would create a mass dependency on third party privacy experts, who know how to set up a phone securely and privately.
I am grateful for projects like /e/OS because it and it’s forum members helped me learn how to tinker with devices that I assumed were locked into commercial systems, where I had a choice of two companies. Linux has done the same for me.
As for browsers, search engines, password managers - all of that is a given and it’s a red herring to throw that into this particular argument, which is about learning that you can do things like flash a ROM or open a laptop on your own, when you never thought you’d be that person. You can see on my blog all the things that has led to for me and the people I live with.
