Mostly just ignore the parent comment, some people are inherently compelled to link a twenty year old business strategy on EVERY Microsoft-related thread.

Nope. In fact, that term is almost always applied to open technology. Right now Red Hat is doing it to Linux and Google is doing it to the Web. See the list of examples on the linked article for more.

Open source means nothing and is same easy to extinguish, it's only more visible when someone is trying to. Microsoft, Google, Apple do open source work for publicity, if you as a single developer want a change in a projects, you submit PR... and wait weeks. First you need to write RFC, at some point RFC will be discussed behind closed doors by corporatisation members, you can have your vote in it on GitHub, but nothing else as we saw once already with MS. All you can do is fix documentation and tests for them, means they get free labour to improve their products, you can have an important repo forked on GitHub.

It would probably be some proprietary extensions in something like systemD. Increase the complexity to code about 10x to eliminate the small devs, etc. Nothing we haven't seen with the open doc standard, ActiveX, Java portability, etc.

You have to think more business like. Why extinguish Linux when every copy running somewhere can give you licencing income. Maybe they'll partner with redhat and provide them something that has to be paid. Unlimited possibilities really.
