I sort of expected some people to react like this. I think you are blowing this out of proportion. It would be easier to write a new script to send out spam (eg: a simple bash script attached to smssend). And yes, some people are going to use this to annoy other people, but all other major cell phones have similar programs, and it obviously hasn't become a problem. If anyone started spamming whole groups of numbers, I can almost guarantee that they would get in trouble with their carrier. This program doesn't do anything ground breaking, it just puts a pretty gui over something 5 lines in a bash script could accomplish (much like the aircrack guis do).
