There are also bluetooth smart objects which are not much better (smartwatches, etc), but at least we have gadgetbridge for those.

Unfortunately there is a real need for these. There's a reason it's like the only bassinet that has an FDA approval rating, as well as why many NICU wards have them for preemies. We literally would not have been able to sleep without it when we had our son, he wouldn't sleep without being either on us or in the SNOO.

We were luckily able to rent one for less total cost than buying one, but for many families I'd imagine the second hand market is the only way they'd be able to afford one. That to me is what makes this introduction of a subscription service even more awful.
