The best way to boycott carbonite is to not use their service at all. There are some real horror stories out there about what happens to a perfectly good computer if you start with carbonite and then try to opt out. Trust me.
Imagine being carbonite right now with YEARS of Rush Limbaugh’s PERSONAL information locked up on THEIR servers somewhere. Think about that.
I wish Rush would have dropped them years ago because you are exactly right. My MacBook Pro has never been the same.
