Funnily they refer to some people wrongly using "Gnuplot" instead of "gnuplot" yet they use "Gnuplot" 23 times in this FAQ.

[layer8]

They don’t say “Gnuplot” is wrong. They even include themselves (“many of us”) in those people that don’t want to start sentences and title words with lower case. My reading of that paragraph is that while “GNUplot” is definitely incorrect, “Gnuplot” may naturally occur due to capitalization, just like with any lower-case noun.

But only because it's the fist word of a sentence all those times.

“ 1.1 What is gnuplot ?

gnuplot is a command-driven plotting program. It can be used interactively to plot functions and data points in both two- and three-dimensional plots in many different styles and many different output formats. Gnuplot can also be used as a scripting language to automate generation of plots. It is designed primarily for the visual display of scientific data. gnuplot is copyrighted, but freely distributable; you don’t have to pay for it. You are welcome to download the source code.”

If it’s lowercase in title font, it should be lowercase everywhere.

Because it's the correct way to spell it. Names are spelled with an uppercase letter in the beginning and all the other letters are lowercase. "I saw John" vs. "I saw john" vs. "I saw JOHN". First one is correct. Even if John tells you "My name is spelled with a lower case j". Or if John writes: "this orange thing is a kaRROT", it's still a carrot.

You can write whatever you want. You can also write "Tis is me bunni and he likes KArRoTs" and have a lot of friends agree with you that's the correct spelling. And it is still generally considered wrong :)

There are many names that do not follow your rule, and generally speaking I'd find it very rude if I told you my name, and you'd go "let me fix that to the _correct_ spelling". For example a name as Angus MacGyver, or Armand de la Cour. Both don't follow your rule. I don't see why that wouldn't apply to brand names as well.

Counter examples: “iPhone”, “eBay”, or people like Norm deSilva [1].

And even in cases where the lowercase starting letter is somewhat accepted, the start of the sentence rule is still left untouched by most writers. Iphones come to mind.

[NullPrefix]

How do you spell iPhone when starting a sentence?

>Iphone is a phone made by Apple

[proto-n]

To be fair, they mostly advise against GNUplot, and mention Gnuplot because of the aversion to start sentences with lowercase (which is also where they use it with uppercase).

Doesn't explain

  8.4 Why does gnuplot ignore my very small numbers?
  For some purposes Gnuplot treats numbers less than 1e-08 as being zero....

[swiley]

I always refer to the GNU one as "GNUPlotutils."
