$3 ink from a bodega
That's actually a fair price for 3rd party replacement.
I used to work at a computer shop, and people only ever bought the cheapest available cartridges.
We also used to do printer repair, do you know how many printers had to come in because of shitty ink?

And anyway, in your example the printer manufacturer has no business tracking your ink usage, whether it's by spying on you and phoning home, or recording this info in the printer's memory.
What exactly is Signal supposed to do here?
They're not supposed to be able to help in any way, how would they determine if a specific user is using Signal for phishing or whatever without decrypting their chats?
Being European would make zero difference here, unless the European service is backdoored.
That doesn't really fit when you realize these are USB 2.0 without e-markers.
In other words: below average specs for way above average prices.

These are headed for the trash as soon as the user needs anything above bare minimum.
