FOSS will overtake some day when people wise up

Show me FOSS productivity software that:

1. isn't a clone of a commercial product 
2. if it is or was a clone, it has in the years since being started as a product brought innovative dealmaking features, paradigms or workflows to the table not found in the application it clones

Of the big five (LibreOffice, GIMP, Scribus, Inkscape and Blender) none even attempt to make their clones push the envelope because their teams aren't representative of their userbase and overlook and/or deny needs they don't personally comprehend. GIMP's color management doesn't satisfy prepress and the project leads have been recorded on video being unable to understand a user trying to explain this to. A 3D modeling program that supports .OBJ but doesn't preserve vertex order is something someone who doesn't use .OBJ would write, and Blender only got vertex order because Reality's author patched it. Sculptris is forever frozen in time as the application where mirroring breaks vertex order, and that was a holdover from when it was FOSS, too. Going back to GIMP, patches have been rejected because the devs felt the user didn't need the patch's functionality. 

To give FOSS its due, there are exceptions: FontForge started out very similar to a very expensive font editor, but has become its own program since in terms of features and knowledge of the user's needs. Calibre is not a copy of anything and works well – except for a few arbitrary decisions about data fields which only librarians cringe at. Sigil is an excellent .EPUB editor/creator which is liberal in what it consumes and conservative in what it emits. Ren'Py is a visual novel engine that could very easily have copied a number of Japanese VN engines, but didn't. If you haven't noticed yet, these products are chiefly developed by individuals, not committees, they do their jobs well enough to have few if any competitors, and their userbase isn't looking to switch. 

Speaking as someone who has used desktop Linux extensively since Debian was a 6-CD ncurses install, built Mythboxes before there were any liveCD distros, was the first wave of Ubuntu and Mint and belonged to the local LUG… Linux itself as a desktop OS had its chance and the world passed it by. You've vastly overrated how much people care about paying nothing for software and even the third world would rather pirate Windows because at the end of the day, people only leave their comfort zones when they see the promise of something unique that's worth the risk. And in case it wasn't clear enough, people who don't play games buy Macs. People who do, buy Windows PCs. The old fallback "you can always run it in WINE" won't apply to 64-bit Windows applications and WINE64 is little more than proof-of-concept code. This isn't FUD, this is the future you chose.

Accept that Linux is in most web servers not running IIS, every Android phone, most set-top cable boxes, and an uncountable number of embedded devices but that it failed to displace commercial OSes which now also cost nothing because 'free' (in any sense of the word) isn't the selling point Stallman wishes it were.
