Very true
A lot of programs are getting shut down, and even the coders being sued because of what their program is being used for.
It's like a car manufacturer being sued if a car was used for something illegal.
Many of the coders don't even use their own programs, they just like to code and are interested in what they can do with a network and being able to do something successful.
My program got pretty far and could do almost everything many of the current p2p programs can do, and I would have kept it going if I had the time but since I was making my money in the hosting and it was needing more and more time, I had to leave my programming.
I didn't actually use it once while it was up apart from testing the network, I also know coders of other programs don't use the file sharing on them, many don't even use the chat if it is available.
People just hear about the p2p networks having to do with something illegal, but there are many uses, as you said.
For example, I was contacted my a few companies looking to use my network protocol for internal file sharing and private messaging...just one of the many things it could be used for
