So you don't know that "the presence of so many options has seemed to be more of an excuse for Google not to have to bother with the stock apps because they'll just get replaced anyways"?
Gotcha.
All you're pointing out is Google is improving Android. That's like me saying, wow, Apple must've not cared about improving their keyboad because they knew they'd eventually allow for third party keyboards.
Rubbish. Google is improving Android as they should be. Have you not watched those interviews/articles/videos about how Material design came to be? Google didn't just suddenly wake up from a dreary daze of "hey we don't need to do anything cause third party defaults! Hooray" and suddenly decided to get their act together.
In fact, if anything, they've been constantly improving their default apps. Gmail, the keyboard (as you pointed out yourself), Chrome, Google Maps, Translate, Google Now, etc. etc. all year long via the Play Store.
You're talking rubbish now. "The presence of so many third party options seems to be more of an excuse for Google not to bother with their stock apps"? Utter rubbish.
I thought you were actually going to point me to something you read or heard about or an interview where a Googler said something about third party options. I didn't realize you were going to cite rubbish.
It seems like you are just looking for a fight. JRSWIZZLE never attacked Android and just voiced his thoughts. He even tried to wrap it up nice and clean but you keep pushing. You keep nitpicking trying to find something to dramatize. Let it go.
