In this type of business where technology changes at a rapid pace a company will not invest in infrastructure if it is marginally profitable, profitable, very profitable or even wildly profitable, only when it is excessively profitable are they willing to take such risks.

Where do you get the standing to make such assertions of what "a company" will and will not do? That's a pretty wide blanket statement about how individual business owners behave.

Also, where do you get the term "excessively profitable"? How is the profit "excessive" (i.e. too much profit)?

At what point is a profit margin "excessive"? 5%? 10%? 25%?

You're using that term as though it's a settled, well-known thing, but it's really very arbitrary.

If you want to argue the content of my post fine, I will not argue terminology though. Pick nits elsewhere.
