It's human nature to get used to something and start to assume that you deserve it regardless of your actions, or lack thereof.
An obvious example is marriage. People work hard to earn each others love during the dating period, then get married and assume they will get to continue to enjoy the benefits without continuing to put in all of the work. And then they wonder why their marriage is struggling.
So I'm guessing it's the people, not the platform.
Really good comparison!
