"Feature" is just semantics, then.
I'll take a pizza ad over Game Center opening up and asking me to make an account every time I play a game, thanks. But unlike the Apple die-hards, I can admit that both a utter crap.
I totally agree and Google's forced G+ integration with the newer G+ Games services is very frustarting too.
No G+ I do not want your crappy me-too social network attached to my gaming apps.
But as is generally the case, I imagine people will hate Apple and love Google for doing the same business practice...
I'll point you to the Apple weather app with the prominent Yahoo! link at the bottom left. This would be more tolerable if the app itself wasn't terrible. I really wish I could delete Apple's apps, why not come with them installed and let you remove and re-add, say like podcasts.
For example, emergency calling functionality was broken for a long time and has been reverse engineered only recently [2].

Apple was not paid by a third party to include it's own software features.
Game Center is like S Voice, a first part developed software that is billed as a "Feature".
Apple has no equivalent to "Pizza Hut" bookmarks that can't be deleted, because they control their carrier relationships better than Samsung who is willing to give their partners the freedom to install and screw up what they want.
Fortunately, Samsung is generally pretty good about letting us users have custom roms, which IMO trumps the Apple advantage for us power users. A custom rom > non-bloated default iOS, to me.
