I’ll start: printers.
I bought an HP in March 2020 when my job went remote and HP bricked it remotely after only 100 pages because I wouldn’t sign up for their subscription program. Ended up trashing a perfectly good printer.
Luckily my library’s close by and I can print there remotely.
All hp printheads are “refillable”. The problem is that the printhead itself is not designed to last more than a refill.
HP doesn’t sell those standalone, all the generic refillable cartridges compatible with HP are hand picked from e-waste in some third world country, then cleaned, primed and sold as “new”
You can buy generic new versions of the cartridge. They are not washed. They are not reused heads, they have never seen the inside of a printer. I have been using them in my printer for over a decade and have never used a rebuilt cartridge.
EDIT: Sorry for the link, these are the cartridges I use in mine. The manufacturer listed them as new, not rebuilt.

DOUBLE EDIT: Thinking about it more, my HP printer is very old so perhaps there’s a mechanic implemented in newer printers and cartridges that I don’t have to defeat, which would make my argument incorrect for that cartridge.
