There are a million reasons to hate Apple, but I don't understand this one. All electronic devices reach a point where the manufacturer stops supporting them. They still work, just no updates.
Using the iPhone 4 as an example, came out June 24, 2010 and was supported until September 17, 2014. That's 4 years and 2 months of support.

Their biggest competitor, the Samsung Galaxy S, originally came out just earlier than the iPhone 4 did, on March 23, 2010. It was supported until January 10, 2012. That's only 1 year and 7 months of support.
Shortly after the iPhone 4 was released, Samsung released the Galaxy S II on February 13, 2011. It was supported until April 9, 2013. 1 year and 11 months of support.

Both companies have gotten better at supporting their devices for longer periods of time, but how can your hate stem from them providing longer support than their competitor when you had your iPhone?
