I guess it probably depends on where you’re going. I went to the UK earlier this year, and my experience was mostly painless. Landed in Manchester, and they basically had self-checkout customs. I scanned my passport and looked at a camera once, and that was it. It was actually more of a hassle and more invasive coming back home and getting back into the country.
They may be idealists that don’t reflect a use case I think is reasonable to expect of the average user, but I would also say that it’s very important to have them there, constantly agitating for more and better. They certainly don’t manage to land on achieving all their goals, but they also prevent a more compromising, “I just need to use my stuff now, not in 10 years when you figure out a FOSS implementation” stance from being used to slowly bring even more things further away from FOSS principles in the name of pragmatism.
