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.


Not quite — a loss leader is also sold at loss, so similar pricing concept, but that’s to get you in the store, where (statistically) people will buy more.
What (many) inkjet printers do is the razor-and-blades model.
Laser printers tend to be less prone to this. You can also get inkjet printers that aren’t using locked-down cartridges, will take tanks of ink and don’t try to keep out competing ink vendors — but keep in mind that while the ink will cost less, the base printer will also cost more than the razor-and-blades model printers. Canon’s “MegaTank” line is one such example.
