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.

Learn BPF... Where?
You're probably interested in https://github.com/xdp-project/xdp-tools and https://github.com/xdp-project/xdp-tutorial. BPF programs are (usually) written in a restricted subset of C, it's not really as simple as nft add rule inet filter input tcp dport 80 accept.

Need guidance: On the insanity of eBPF and XDP
xdp-tutorial is heavily outdated, and doesn't use the current headers and neither the current libbpf.

BPF for Hid Drivers
In the same way out-of-tree kernel modules are enforced to license themselves as GPL if they intend to use a lot (if not most) of the available functionality, eBPF programs fall under the same restrictions.
bpftool[0] allows to see which the programs are currently running in your system, their bpf asm instructions and whether they are GPL-compliant through `bpftool prog show`
Of course, we still need companies to actually release the source code of their eBPF programs somewhere for the promise to be fulfilled.

How to tell what created/owns each BPF program running in my system ?
Your distro might not ship the newer version but source is available on Github so you don't have to pull the entire kernel repo to build it.
What are some alternatives?
