You can't be the underdog forever. Once you win, it doesn't make sense to focus only on belittling your competition. Apple's brand is, and has been, about trying to make the best stuff.
It is the very worst kind of behavior that people pejoratively describe as "hipster" to look at an advertisement proclaiming "Hey, people really like us" and respond with "That just makes me hate you more."
Today, they have a product every other manufacturer wants to beat, and so their strategy is reasonable, showing that they have not been beaten yet, so this kind of ads. At the time, they were trying people to adopt an ecosystem (the Mac) that was anecdotal in comparison to the PC, totally different exercise..
