> it doesn't count as malware unless it resists switching search providers back
Bullshit. If installing software changes random settings on my computer, it's malicious. If it was a default in the app itself, that's a different matter.
This actually might be a first for OS X freeware. Certainly I've never seen (or heard of) a 3rd party toolbar/whatever bundled into an OS X package before this.
But that person surely needs VLC instead, which too may come with 3rd-party crapware installer if you're not careful.
