Did you read this part?

You see people use "Gnuplot" quite a bit because many of us have an aversion to starting a sentence with a lower case letter, even in the case of proper nouns and titles. gnuplot is not […]

Most of us don’t care about forcing the first letter to be always lowercase, and in fact feel it’s a lost cause. But I agree that after such an explicit clarification I would expect to see “gnuplot” everywhere in the official documentation, except for this particular excerpt and when they refer to “GNUplot”. Otherwise it is clearly inconsistent with what they are explaining.

Yes, I also read the body text after the numbered heading in the prior excerpt, which makes two different choices in sentence-starting position in sentence case. But what I was responding to was the inference of a rule bases on usage in “title font” (which seems to be a reference to title case), not a complaint about the inconsistent use in sentence case. Hence, the except you provide here isn't really germane to anything I've said.

They very correctly mix it to show that it does not matter. Better make some plots then bikeshed this to death.
