Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Wouldn't it be crazy if amd or intel turned around and started making RISK-V based processors to compete with arm?
There is code that describes the processor, the VHDL is also open source. You can get the some similar implementations for older ARM implementations but you may have to pay to use them commercially.

If you're willing to go REAL slow, there's still FPGAs. Something like this perhaps. Adoption would be pretty damned limited though, so your point stands.
