I don't condone the terrorism that the US has faced, I don't condone the cowardly acts or terrorists in any way shape or form.
However, I am from a country that saw continual terrorism for decades, and that doesn't include Hitler's part, and people have to keep moving forward every day. You don't have to forget in order to move on with life.
A timer for a phone is such a generic, it's not like someone asking where to secure some uranium or whether to connect the blue or red wires first.
A timer is an app. I suppose some people feel that it would be wrong to ask for input on what type of fertilizer to buy for your rose bushes too.
Just yesterday, I has a US customer ask us to design some emergency response alarms for his workers in the oil fields. I went and bought 500 timer kits for my techs to engineer a solution that sends an alarm to the head office if a timer in a workers truck is not reset at specific intervals, meaning he's left his job and returned to the truck safely. The guy at the electronics distributor didn't seem too concerned but the news was on in the store showing the efforts to sort out what the hell happened in Boston.
