Google Pixels with GrapheneOS were the only Android phones to withstand the backdoor software the FBI used to access the Trump shooter's phone.

My USB KVM switch uses them

That's actually illegal in the UK, to charge a fee for card use. Just means everyone pays more in increased prices, although most people in the UK use card for everything so for the population as a whole its probably a money saver, if not a privacy saving policy.

This decision was helped by moving to GrapheneOS and losing Google Pay, definitely. (And Degoogling for other reasons at the same time). If I have to carry a card I may as well carry cash, a few folded notes are the same footprint as a card and as I mentioned, I try not to break notes if I don't have to, so I'm not carrying change often.

Anyone in a 14 eyes country is essentially impossible to achieve zero footprint, but assuming they're not actively looking into your network packets or searching for you on CCTV its feasible to have a relatively low footprint. I'm essentially trying to eliminate as far as practical, any data points I'm just giving away for free for no reason, especially to corporations and advertisers.

No, same in the UK. How could you force them to take cash if they don't want to?

Plenty of cash only businesses in the UK that engage in this, although of course just because a business is cash only, doesn't mean they're a tax dodge.

IMO the two things are separate: it should be the tax office that does audits to catch this. It's not very hard to see a vape shop that makes £500 a month with two top model BMWs outside might be dodgy.

Yes, even the buses and vending machines and car park meters and public toilets have tap to pay. It is certainly very convenient but I think it does encourage spending more, and of course it means literally everything you do is tracked. Luckily I've found that most places still do accept cash but there are definitely a few who don't.

Then they enforce the chipmakers to put backdoors in the chips themselves

Works fine on an 11th Gen i5. Not fast but not slow

As a web dev we do try to accommodate userCSS for accessibility reasons but often font sizes are tuned to what they are for a reason. I'd guess there's a line height issue here.

Also no one ever mentions that the industries are building products for the public. They don't just release CO2 and use electricity for fun lol
