The competition has moved inside Linux. The large companies all maintain their own patch sets. There are still ways they believe that they can make OSes better, they just don't believe they can compete with Linux in all the other ways, so they just write their own modifications for it instead.
Which is absolutely wonderful, because Linux is licensed under GPL, so the best improvements end up in the main tree and everyone benefits.

- bryanlarsen 9y agoThat's a great example of https://news.ycombinator.com/item?id=15772233 https://news.ycombinator.com/item?id=15772233 (currently also on the front page), where something appears superior on the surface, but there are good reasons why it didn't "win".
- srcmap 9y ago"grsecurity/PaX" didn't show up in the main tree but is alive in a different branch or as patch. Various distributions and users are free to enable and use it upon demand. It kind of prove Linux kernel is not mono-culture and natural selection and evolution are happening. I believe the AOSP's kernel patches are also not mainlined - also proof Linux kernel are evolving very healthily.
