Examples of proprietary control

[Carsten Agger]

I'm doing a text about the potential damages of proprietary software and
have mentioned the "celebrity cases" of Windows installing "Windows
Genuine Advantage" with the automatic updates, Apple reserving the right
to zap any and all iPhone Apps it doesn't like and the Amazon Kindle
censorship case - trying to argue, obviously, that if all software was
shipped as free software as a matter of course, that kind of behaviour
would not be as big a problem as users and organizations would be able
to change it.

Does anyone know of more striking cases, possibly a list, of people who
have been badly bitten by proprietary software. (There's the standards
issue, of course, but that deserves to be treated apart).
