Stupid question

In the past weeks i posted some issues which could be an entry for evil people into efa.
Up to now no comment at all to my posts.

Now my questions are.

- Is this the right forum to post ?
- Is there an interest to have this information here ?

Thx
hoping to some feedback.

Which distro should we focus on for eFa? :dance: :think:
Hi
in the light of redhats announcement to close the source . Wouldn`t it make sense now to focus on Debian or Ubuntu LTS ?

Re: Next Major Release OS Version Survey 2020

Hi
based on the current decision of Redhat to lock down their repositories i voted for Debian.
CentOS is and was not bad. But with this mindset you can no longer trust redhat. Or should we say IBM ?

Ubuntu might have the same attitude next week and CentOS Stream is like gambling .

So natural choice is Debian. One the other side why isnt devuan on the list ?
