What are you asking here? Is the question about uninstalling Chrome from a PC? A Nexus? Or not supporting Chrome on the site? What's an evite? I've certainly REMOVED Chrome and reinstalled it on occasion because of some issue, but never noticed anything weird happening. Of course, it wasn't off the machine that long. Don't have the option to remove it on the Nexus without being threatened that things will stop working. Of course, have tried three other browsers on it and they weren't remotely as good, even the ones that supported Flash.
Ya know google's working for the NSA, right...
Evite is just an invitation that is hyperlinked in a email to download then run a flash? I guess.
