Analysis of the 2nd Log4j CVE published earlier (CVE-2021-45046 / Log4Shell2)
I'm sure they mean well, but I'd highly recommend to every user to be very careful about using services like this.
Do you know whether you can trust them? Is their operations mature enough for handling the attacks they are guaranteed to receive? After all, a system receiving requests by folks suspecting they are vulnerable, makes a highly attractive target itself. In fact, I wouldn't be surprised if we see services of this kind provided by malicious actors.
Really, people should just update, or only use offline tools for analysis and mitigation like [1] which they can audit and run locally.

Hackers exploited Windows 0-day for 6 months after Microsoft knew of it
I don't think that's a good example. While Apache devs are volunteers and Microsoft devs are employees, they were criticized for their slow response time and seeming lack of urgency until it was far too late.

The Dedicated Maintainers Behind Lesser-Known Open Source Projects
However, there are many open source projects that are widely used but not well-known, including cURL, ImageMagick, MyCLI, Homebrew, Apache Log4j, and OpenSSL. This article will take a closer look at these unsung heroes of the open source world. I do not want to give them a business model or financial advice in this article. This largely depends on the author's personal experience and values. I just want to raise more awareness about these open source projects.

Apache POI Setup Logging Error
What you need is log4j-core, what you downloaded is some kind of connector between log4j and JUL. Tbh I don't know what JUL is, but that's not important. You can get log4j-core on from the official website - https://logging.apache.org/log4j/2.x/ or in maven repo. In case you're not using maven, I highly, highly recommend you using it for managing your dependencies.

Log4Shell Still Has Sting in the Tail
> When it was first revealed in early December 2021, the Log4Shell bug was described as one of the most severe security vulnerabilities ever.
> The Apache Software Foundation, which maintains the open-source tool, quickly released a patch...
Apache horribly mismanaged this and did not release a patch until it was already widely known and being exploited in the wild. They also messed up and had to release several subsequent patches to actually fix the vulnerability.
Remember: this vulnerability was disclosed to them in November.
