|Considering the following markets|
- Embedded / IoT
- Server / Web / Cloud
- Gaming Console
- Enterprise Software
In all the markets except desktop open source software has > 50% market share.
If you consider Mac and Chrome OS, Virtual Machine Installs, Desktop reinstalls, people using both Windows and Linux at $work ... I would wager that FOSS Desktop Market share is well over 15%.
Based on that would you say FOSS has won ?
On a side note would you consider carpentry / IKEA as a model of OSS, where openness is obvious ?
Where FOSS has failed IMO is closed computing and closed data.
Reducing a general purpose computer to a vendor purpose computer by means of special firmware (the Apple CPU being the new culprit on the block). This also happens on the cloud. This is why Mac or Playstation are still considered closed source as compared to Android which allows you to install ROMs for the most part.
For some strange reason it is acceptable for data to be closed source. It is clearly where the money is. The user owns the data and the more I look at it ... the idea of transferable copyright for perpetuity is absurd.
