It sounds strange because its a horrible thing to say. GOS is not unbreakable but its technical capabilities being impressive dont change the harm that people have caused GOS. What demotivates them is the attacks against them and you are explicitly giving advice that allows this abuse to continue. Do you see the issue there?
Only ~400k people use GrapheneOS at this time, but that will grow, especially with the Motorola partnership. But number of users doesnt make the abuse hurt any less. Many need this OS, as you claim, so you should be far more upset with the abuse it receives and help counter it rather than suggesting apathy as an option.
