There are screens outside of the installation before you select a Custom install that could have been checked by default. Either that or there can/had been another screen after the installation and boot that had chrome pre checked.

Eight updates ago is a relatively long time ago in terms of a program update, but we need to be alert and not click to move on.

I’m totally against pre-checking requiring the user to Opt Out and not pre checked to Opt In. So we really have to slow down and read what is presented and that applies to other program installations also.
