From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I believe it's 1% for access to the "entire post-open ecosystem", rather than 1% per project which would be unreasonable. So you could use one or thousands of projects under the Post-open banner, but still pay 1%.
It will take years to develop the post-open ecosystem to be something worth spending that much on.
