I’m not working for Icinga.
First of all the nice part:
the old packages are still there:
https://packages.icinga.com/centos/8/
https://packages.icinga.com/centos/7/
but since this was always meant for centos the updates are no longer available since centos7 and centos8 are EOL.
I used google translate to read your post and though I was able to understand the basic meaning, sometimes the translation to german was a bit off, that is not your fault, but by writing it in french you restrict the content to a smaller group. maybe consider a rewrite in english.
Icinga is an opensource software published under the GPL. this does not mean that that packages are available for free.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.

I’ve been running Icinga on all my servers (mix of Rocky Linux 8.x and 9.x) for the last five years or so.
There were never any official free icinga2 packages for EL9. How did you do that?
The paid subscription topic is from November 2022. It is not a popular decision, but also not a recent one.
And the last part:
if you trust someone completely different to build packages for you, you can look at this post:
I also built some packages myself and it costs time, lots of time, and as we IT-Professionals know time = money. Every packages provided by Icinga needs a build pipeline, maintenance and testing and so on. So it is their choice for which platform the packages are available.
As it is you also decide which content is available for free on your blog and which content is behind the “university enrolment paywall”
