Why didn’t you bring a small notepad, easily fitted in a pocket or small bag to take notes of things to remember, instead of a camera? Dumb phones may have had note functionalities too, I’m not sure.
Stallman gives plenty of alternatives instead of just forbidding technology, but you’re gonna brand them ‘non-viable’ so there’s no reason to give you a list.
Do you also consider remembering to take your wallet and phone with you a hassle? You’re creating an issue where there isn’t one.
But OK, have a smartphone and use it to take photo-notes, I do that too. But I also try to use libre alternatives for software even if they are not as good as their proprietary counterparts, because that’s the right thing to do for a lot of reasons.
Also funny that you’re mentioning lawnmowers, because tractors have a huge issue with proprietary software, with farmers having to resort to hacking their (bought!) vehicles in order to repair them, to avoid paying thousands of dollars to John Deere for “authorized” (read: extorted) repairs.
You agree that the corpos are “evil” and yet you do nothing to avoid using their software, you’re not willing to be discomforted in the slightest for a good cause. That’s worse than Stallman’s approach, in my book.
