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.

At Microsoft, years of security debt come crashing down
They make detailed arguments for their position, for example, https://madaidans-insecurities.github.io/
The people who maintain the Linux security is fine also make arguments, but those arguments are much less convincing, such as the frequently-made argument that the fact that Linux's source code is readily available at no cost to anyone who wants to search it for security holes means that Linux's security will tend to be better than the security of systems whose source code is held secret.

My privacy journey -thanks to this and r/privacy sub AND how can I make it better
That's somewhat telling and can be used to "track" you, consider reading on non-Reddit privsec learning resources like Privacy Guides itself which you already know, PrivSec.Dev, madaidan's Insecurities and the like.

super secure phone with vpn
Considering the offer is legitimate (something I won't comment on), you shouldn't do most of these things, in my opinion. Don't mess with what'll be other people's phones. Sell them Pixels pre-installed with GrapheneOS and print papers with Auditor attestation instructions and maybe a few QR codes directing them to relevant documentation and privsec learning resources, such as the GrapheneOS documentation first and foremost, Privacy Guides, madaidan's Insecurities, PrivSec.dev, Seirdy's Home, Wonderfall's Lab, etc...

PoC to demonstrate root permission hijacking by exploiting "systemd-run"
No, the OP was not sent any harassment, the OP _did_ the harassment as it can be seen in the tweets. I mean, they are right there, just click on the links you shared. One of the OP's followers even openly called for the assassination of the project maintainer, and you have the galls to defend him? This is truly deranged stuff.
And again, there is no "vulnerability", there is simply a person that doesn't know how Linux works and has learned something new. Which again it's fine, nobody knows everything and we all learn new things everyday, it's just that normal and sensible people don't use that to make grand claims on social media and start harassment campaigns culminating in death threats.
Professional security researchers responsibly report real issues using the appropriate channels, such as defined at: https://github.com/systemd/systemd/security/policy this is not the work of a researcher, this is a grifter looking for self-promotion on social media.

Run0 – systemd based alternative to sudo announced
> 3. even `adduser` will not allow it by default
5. useradd does allow it (as noted in a comment). 6. Local users are not the only source, there things like LDAP and AD.
7. POSIX allows it:

Systemd Rolling Out "run0" As sudo Alternative
> I for one love to type out 13 extra characters
FWIW, systemd is normally pretty good at providing autocomplete suggestions, so even if you don't want to set up an alias you'll probably just have to type `--b ` to set it.
> I wonder what random ASCII escape sequences we can send.
According to the man page source[0]:
> The color specified should be an ANSI X3.64 SGR background color, i.e. strings such as `40`, `41`, …, `47`, `48;2;…`, `48;5;…`
and a link to the relevant Wikipedia page[1]. Given systemd's generally decent track record wrt defects and security issues, and the simplicity of valid colour values, I expect there's a fairly robust parameter verifier in there.
In fact, given the focus on starting the elevated command in a highly controlled environment, I'd expect the colour codes to be output to the originating terminal, not forwarded to the secure pty. That way, the only thing malformed escapes can affect is your own process, which you already have full control over anyway.
(Happy to be shown if that's a mistaken expectation though.)

Ubuntu 24.04 (and Debian) removed libsystemd from SSH server dependencies
Maybe it was because you weren't pointing out anything new?
There was a pull request to stop linking libzma to systemd before the attack even took place
https://github.com/systemd/systemd/pull/31550
This was likely one of many things that pushed the attackers to work faster, and forced them into making mistakes.
