Imagine that you are looking at something similar to what actual bank atms are facing,which is some mechanism to overlap and record details or hijack the system. Its very interesting and most likely quite effective whatever it is they have sprung on the atm due to the lengths that you say they are going to get inside. Imagine it will become apparent later on and not right away as the data is collected.
not that easy i guess. usually they copy your card, which they still could do with every other atm, so why bother to break in and try with this one? the btc part works with displays or paper printouts, which should be harder to manipulate.
but that doesn't matter as the atm isn't used anymore anyway.
You miss the aspect that bitcoin is not seen as real money for a lot of jurisdictions,so punishment would be less and harder to track down.
It would also work just the same as hijacking a regular atm and that has been shown to be quite easy with parts found on ebay.
As to the matter about it not mattering anymore,this is a open discussion and a potential warning for other service providers. So end of the day the warning and thread do matter to those that frequent bitcoin atms.
