Me go first:
- Most printer: we all know …
- Keurig: a coffee pod machine that use one-time pod. They once refuse to use third party pod with a chip.
- Juicero: a luxury juicer that squeeze juice from repack pod (which you can squeeze by hand). The machine will only work with pre-pack pod. You cannot make the machine work with your own food or vegetable.
You know any ? Any product, startup, dead or alive.
You mean items that should be generic commodities, but which companies customize in order to lock you into their ecosystem, or otherwise restrict what you can do? Like printer ink cartridges or Keurig pods with ID chips, as you mentioned.
