I more and more tend to not buy any network-connected product if there's no open-source firmware to run on it.
(Phones is one notable exception. I need contactless payments to work.)
If you call up your contactless payment provider, most will send you a physical device that will do contactless payments on its own, for free even. You can tape it to the back of your phone, or anywhere else for that matter.
Good thing some tapos do have alternative firmware like thingino.
