What are that kind of decisions based on? This is a repeat of the Samsung Note (?) fiasco, which, as someone else correctly stated, is just going to cause manufacturers not to disclose defects.

What is the actual criterion they used to determine that the device is dangerous? Did they estimate the likelihood of the battery catching fire, or did they just rely on manufacturer information? If it's the former, where can I see the numbers (and compare them with other devices?). If it's the latter, will I be safe forever to bring cheap no-name electronics on planes?
