I'm pretty sure these devices are not properly EMI tested or rather, they were, but the manufacturer cheated (as everyone does with this kind of stuff). You can, and IMHO should report these kind of EMI to the proper authorities. Devices like this should not be sold and in nost european countires are actually illegal (there is a law against "knowingly" transmit in a band you are not licensed for). I don't know other countries, but at least in Switzerland, the BAKOM is usually quite happy to hear about these things, and test devices in their own lab... with nice fines for the offending company for not properly testing their products.
Depends. If they use approved frequencies and powerlevels it may be fine. In this case it doesn't look like it. There are telemetry frequencies allocated, they should use those.
