I think your being a bit harsh on the tech 'savvy' here.
Lets look at it this way:
They are being denied the right to send files that can contain a payload. Its not their fault everyone else isn't as uber elite, its not their fault if someone gets infected and becomes part of a botnet; spamming/Ddos'ing/ stealing data.
Its not their fault that the infected will have a bad experience and leave the ISP.
Its not their fault that cyber crimes will raise.
Its not their fault or problem that though being 'tech savvy' they rely on a ISP mail service.
Its not their fault that mummy didn't hug them enough and now they find any **** weak reason to whine, bitch and moan.
Its not their fault they have no choice in providers and can't find another one.... Oh wait!
