This also extends to other products. Don't use your personal Gmail to do 'TOS violating' things. Better yet, separate it as much a possible with different devices, VPNs, etc.
I don't think anyone here is blaming the users, the comments are saying they shouldn't be surprised.
Users blatantly violate TOS > company bans account > shocked Pikachu face
I agree with the above commenter that they should have expected this. I remember watching SnazzyLabs video about Beeper when it was about to come out, and the video essentially said 'people have been doing this for awhile, I don't think Apple will care about Beeper' and I thought oh yes they will.
Do I think Apple is in the right here? No. Am I surprised they're taking this action? Also no.
