While the enshittification of the Web (and beyond) might seem far greater than any individual can even make the slightest dent in–you, we, can deshittify the Web one small piece at a time. Something you like or use or do that's become enshittified? Disenshittify it.
A handful of times a year, for years, I ( John Allsopp ) have needed to created a QR code. My go to has been a service from a well known link shortener. Then recently I used it to create a new QR Code and went to download it only to discover it was now a paid service.
So not wanting to pay a non trivial amount of money on a subscription basis to create a QR Code a few times a year I went looking for alternatives. The first few results on Google Search required at the very least an email or account setup. Every service had as least some advertising or analytics (usually both typically multiple of both).
