The fact that you consider the observation obvious, is a sign that you were possibly trolling. You were probably being intellectually too lazy to make your point without resorting using tactics like calling your own opinions seemingly obvious.

It is not obvious that increased competition leads to declining margins. Often increased competition validates the market, and increases consumer demand far more than the effect on pricing. I have seen it in my own industry, where our sales increase when a competitor launches a big ad campaign.
