Disclaimer: I avoid Chrome browser exactly because I don't have enough information to know if they really "aren't evil." I don't claim there isn't such information somewhere, just that I don't know about it. My worries are exactly because their installers install more like a malware than like clean projects ("no we aren't going to let you to simply download executables, just click here, give us administrative privileges and enjoy when we download what we want and change on your machine what we like").
Anybody who knows more?
