None I can think of.
The whole thing, PLUS it inflicts surveillance crapware onto your Mac. That's evil.
If you too uninstall this crapware (via the kindly provided Uninstaller), be sure to do a Spotlight search in BOTH your /Library/ folder AND your ~/Library/ folder for leftovers. I found a SLEW of DivX .plist files polluting my library folders, including one nasty file still residing in one of the Launch folders, which is an evil thing to do. Dump Them All!
Oh and talking about evil: While the uninstaller is running, it attempts to phone home to the DivX site to look for updates. Can you imagine? It wants to UPDATE your installation as you are uninstalling it.
WHY did I uninstall the DivX crapware? Because this recent 'Conduit' infliction garbage during installation is The Last Straw. I've had enough. I don't ever run into DivX video on the Internet any more. I don't care about DivX video any more. May DivX rot and die. I think we already have more than enough effective video formats without having to bother with this unimportant format family.
However, I am keeping a copy of the current installer around for just-in-case. But I highly suspect I'll never need it and will have forgotten why I ever bothered to keep it.
