- I'm glad that other CAD solutions exist, but AutoCAD is by far the most popular and used one. It's de-facto for many applications and industries and there's no way you can avoid DWG in certain situations. Does it work under Linux? No. Will people try to install Linux just because for them it's all new and shiny? No.
- Android is not Linux. Fine, you have just reiterated this.
- Photoshop and Corel Painter are the two most used instruments amongst photographers in the world. You can argue ad infinitum that GIMP is usable, but GIMP offers a completely different workflow, lacks many crucial Photoshop features, and people just don't want to learn new instruments when there are the proven ones which work excellently (I don't even want to touch the topic of proprietary RAW formats support in Linux or lack of it - do you really think people will break their heads to make RAW files usable just because Linux costs $0? The OS cost is negligible for most people. Their professional instruments costs thousands of dollars and those instruments don't work in Linux).
- It's difficult to realize for you but there are people different than you and such people want to play triple A games without too much hassle. They want to play their favorite games and absolutely most of them are not available natively for Linux.
- "incorrect and false statements" - would you care to be more specific? Or your stance is, "I don't like what's written there so it's wrong"?
Stop deluding yourself, people won't try Linux when basic things in Linux don't work or they are in a half-working state (sound robustness/hardware support/lack of consistency - Gnome3/Unity f*ck ups just to name a few).
