I use these for printing my shopping lists, I like synced lists (in Todoist in my case), but hate walking through stores with a device in my hand. The Ökobons have the added benefit of me being able to scratch items off the list with my fingernail. Also the blue is cool.
These days, we don't use this any more. First, because we now use primarily original Boca printers and are allowed to use the official drivers, and second, because we do 99% of printing from Android devices, where we also handle the protocol conversion ourselves, but it's a lot simpler without CUPS. Still, was a fun ride doing this back then!

(Author here) Yes, every kind of lottery/raffle is a possible solution but only with strong identity verification to avoid double-entry and hence only with sacrificing privacy, as mentioned in the article.
Our CI rans our test suite against all of SQLite, MySQL and PostgreSQL which worked well enough that I can only remember one or maximum two bugs caused by this, but yes, wise words.
