When you compete with someone, you become more like them. The longer you compete, the more you resemble each other. Eventually, you turn into clones of each other. It doesn't matter who starts competing, or even if the decision to compete is consciously taken. Market forces may force you into competition with someone or something, or consumer / viewer expectations might. The end result remains the same. Competing parties lose their identity to each other like victims lose their humanity to the vampire's bite by turning into vampires.

Facebook didn't have a feed architecture until it started competing with Twitter. When it got one, it became a little more like Twitter. Twitter, in turn, enabled the Like function in the form of the Heart button. Facebook then got the Share button on posts. Eventually, all that separated these two formerly distinct platforms was the fact that tweets could only be 140 characters long. But now that too is gone. Now, for all practical purposes, the two social media giants do the exact same thing and nothing distinguishes one from the other.

Wix and Squarespace were two website building tools that competed with each other, adding more and more cloned features. Now there is hardly anything that marks them as different.

Coke and Pepsi had distinct tastes until Coke started competing with Pepsi and made itself more syrupy. Today, they both taste pretty much the same.

Hindus took pride in the notion that they were peaceful and civilised. They criticised Islam for being violent. Now, after years of competing with Islam, there is hardly any difference between the two as far as advocacy for violence goes.

Who you compete with changes you, and in time, defines you.
