I wouldn't pay attention to Reddit comments like that.
The way I look at it, I was providing a service. For some people time is money and the time for them to secure a proper phone, learn about GOS, setting up their computer with the proper drivers to install it and setting up the phone is a significant cost in time. This is time they could be making more money (than it would cost to hire someone to do the above) or could spend doing other things like spending time with family, or recreational activities. I know a few directors and executives at my employer and they work 60 to75 hours a week. They use all sorts of services a "regular person" could do themselves (house cleaners, grocery delivery, vehicle cleaning and maintenance etc.) because their time is more important than doing these menial tasks in addition to their job. And it's not just executives that use these services, a lot of "regular people" do as well for their own reason.
Many of the naysayers look at the situation from their own perspective. "Well I bought a phone and installed GOS myself, why would anyone hire someone to do that?". Might sound harsh to say this, but those people have a limited view and likely will never be entrepreneurial.
They themselves probably use many services (go to restaurants, hire a plumber etc) that someone else with different skills could easily turn the table and say the same thing (well why don't they just cook food themselves, well why don''t they just unclog the drain themselves).
I think if you keep your overhead down, and start out slow then you could see where it goes. You might also start out consulting people on how to set up GOS on their own phones and installing their GOS devices for privacy. There is a lot of research involved in setting up a GOS device to be private, secure and everyday functional for the needs of an average person.
And like @matchboxbananasynergy said, make you sure you are clear with your clients you in no way represent or are directly involved with the GOS project, are not involved with developing the OS and are only a 3rd party installer. Any support would have to be done by you during the support period you define, and not the GOS team.
Good luck with this!
