Gotta disagree, John. The Start Screen reaches out to the internet to snag "news" and "tips" and whatnot. That's kind of the definition of "phoning home".
Fortunately it can be disabled by turning off the start screen but I would prefer to be able to turn it off WITHOUT turning off the start screen.
As far as not hopping on updates immediately? Well that's a pretty easy one to figure out. Sometimes things get broken and can affect work in progress. For those with CCC installed not such a huge deal I guess BUT I (and others) don't use CCC specifically because that is a TOTAL "phone home" scheme... and itself has some silly stuff going on.
Not trying to give you hard time (obviously) but those are good reasons based on how it all works (particularly for us offliners).
These aspects of the new model are indeed things I do not like... at all. But at least they can kind of be avoided without losing crucial functionality.
Many other companies do not even provide that so although I don't like it I'll commend Cake for at least giving us an "opt out"... even if it is a bit of a futz around.
Cheers.
