The SOS button is pressed without a true emergency.2. The device malfunctions, loved ones at home get worried, and the SAR gets called out to search when no actual emergency exists.3. Carrying the device leads to overconfidence and people attempt routes they otherwise would not feel comfortable doing.
1. I don't know about other models, but with my Spot it would be serious user error to press the SOS button accidently, it requires opening a small cover marked SOS to access the button, all other buttons are on the face. But if you mean that someone would call for help just because they have a device and are in a tough situation (like an unplanned bivvy) that otherwise they could get themselves out of or just suffer through; I am sure that has happened and will happen with increasing frequency as more people have the technology. It already has happened with cell phones, at least in my area. That is the best argument for two-way communication.
2. I have instructed my contacts to NOT call SAR if no OK is sent, for that very reason. But your scneario could happen without that kind of information for the contacts. The OK signal should not be used for Rlown's deadman switch use, as you say the device could fail, or in my case my memory might fail and I would forget to send an OK.
3. I am not sure at if this would be the case, I suppose it would depend on personality, the same might be true for bringing a partner.
