When Adobe released the CS suite, they added a revision control system called Version Cue. I had mixed feelings about it, but at least it was off by default.
When they released the CS2 suite, they turned it on by default, without any regard for security. I was less than thrilled:
The only nice thing I can say about it is that it doesn’t add a new rule to the built-in Mac OS X firewall to open up the ports it uses.
Care to guess what CS3 does? If you guessed “adds a new firewall rule”, you’d only be half right. It adds a new firewall rule, and then turns off the firewall. That part’s a mistake, obviously, but silently modifying your firewall settings to turn on an unsecured file server is unforgivable.
[Update: Adobe acknowledges their mistake in turning off the firewall, but does not apologize for silently turning your machine into a server and sharing your documents]
