I feel like people choose arguments that suit them. It's not like Samsung didn't withhold features from the GS2 that the GS3 got. S-Voice for example was not available for the S2. Smart Stay for example was not carried over despite the ICS update on the S2.
The difference though here is that Samsung and the other Android manufacturers aren't claiming to be clean on that issue like an iPhone 4 user bragging that they have the latest iOS 7 update on their phones.
It like a Republican preaching hate against homos on the Senate floor, only to find out he was fucking a male page or hobbling his feet and body parts in the restroom against another dude only to find out that he was actually a closet homo himself.
Do democrats do the same? Sure. But most of them don't claim to be innocent like Republicans are on that particular issue.
Or in another case Newt Gingrich impeaching Clinton in the name of morality while he himself was having an extramarital affair while his wife was recovering from a cancerous tumor.
It's nothing new that manufacturers withhold software features from older phones to encourage you to buy a newer phone and to show that separation. And acting like the iPhone 4 got no new features despite having OS updates is disingenuous.
And acting like Android phones got no new features because they're not on the "latest" Android update is just as disingenuous and dishonest.
The difference here now is that Google packages most of the updates into Google Play Services, and it's apps(Google Search/Google Now, Hangouts/Messaging, Google Keyboard, etc) so there's little need to.
Could Google have done like Apple and release Google Now(ala Siri) and market it as an exclusive feature for only Android devices made after Summer 2012? Absolutely.
Could Google have released Hangouts(ala iMessage) and say you device must be running the latest Android OS(Kitkat or JellyBean 4.2/4.3 and above) to get such a feature? Absolutely.
Can Google use Play Services to push and install Twitter app to all Android phones today and automatically claim that they have "Twitter integration" like an iPhone 4 user bragging that they have the latest iOS7 updates and features? Absolutely.
Can Google use "Google Play Game Services"(which is comparable to iOS Game Center and works on Android 2.2 and above) instead of doing like Apple did for "Play games" which requires an iPhone user to have the latest iOS7 update to get such a feature? Sure.
What difference does it make that an iPhone 4 user is bragging that they have the latest iOS 7 update with Play Games, Notification Center, Keyboard shortcuts, or iCloud when an Android user on Gingerbread can get those same exact features today without requiring an OS update?
Could Google follow Apple and claim each year is a +1.0 release like Apple does and start a "latest version" wars like how Chrome and Firefox desktop browsers seem to be racing to who can get to the magic version #100 first? Absolutely.
