If I were to maximize Sublime on Windows, Linux, or OS X (green button), you still have the chrome from the windowing system and the OS's menu bars.
Also, the parent comment makes no claim Apple invented anything, he/she is just drawing a comparison people would be familiar with. Frankly, it's more than a little annoying to me that you have to distract from the topic to make completely non-constructive dig at a company you seem to dislike and completely miss the point of the comparison in doing so.
Why did Apple make a Full Screen feature in their operating system? Minimalism and simplicity.
Why does Firefox have a fullscreen option? Because most browsers had that option and it's a useful feature once in a while. Not a compelling reference.
They had them well before full screen on OS X became a "thing".
Your reply misses the point that the original comparison was flawed. It was like saying "A bit like why Apple added ASLR" or "A bit like why Apple added CUPS". They invented neither and were first to market with neither.
I don't use sublime, but on Linux (Ubuntu GNOME) when you full screen an app the window decorations are hidden and so are the status/window menus.
Edit: before you downvote, please explain why??

Is this built in to the stock ubuntu releases? If so, what version?
I'm using Firefox with the borders set off right now. This gives me a window with no external chrome (no border, no titlebar, no buttons, no scroll area) but set with the standard KDE application bar (which I keep at the bottom a la Win95).
Indeed before Firefox ditched the menubar I used an app to get the same effect pinching a lot of real-estate back (titlebar, menubar, buttonbar). It's interesting that things have moved this way, though not surprising.
Not sure about the Unity interface as I have limited experience with it.
Yes, if you maximize. However if you go fullscreen (F11) the chrome disappears.
But yeah, apple is far away from having invented it
