These cameras are extremely suspicious -- just follow the money. I bought some cheap Chinese cameras in 2020 that by default send the video stream to a Chinese server, which you can watch with an app on your phone. The cameras were about $40 on Amazon, so my guess is the manufacturer was getting paid maybe $15-20 for them.
Bandwidth to and from China is not that cheap, and you could be running this stream 24x7. The streaming service still works 4 years later even though the company whose name is on the camera has vanished.
So, who is paying the server/bandwidth bill? The camera is too cheap to afford indefinitely providing this service, so you can only presume that you're paying in another way. Probably there is some third party in China that the camera manufacturer makes a deal with. The camera manufacturer may even be getting paid to pick a particular provider.
