2.9.5 should not be available to download due to it being broken.

You understand that when you see a directory listing such as when you browse the Linuxcnc repo that those listings are created by the web server on the fly ? So I'm not sure if Apache et al allows for what your suggesting, or whether the Debian repo model allows for the behaviour you suggest.
Whilst saving a few dollars it could be an administrative headache.

Twice the money is still zero.

Your major issue is a lack of knowledge of how things work. First being not understanding how directory listings are produced by a web server. Secondly not understanding how a Debian repo works, and thirdly not bothering to find out how these things work.
Hoenstly, and I'm trying to be as diplomatic as I can, you have a low knowledge of how and why things work and yet this doesn't stop you giving out adice based on your knowledge. A classic example was when you suggested apt was stupid or frustrating or something similar for not installing packages due to version mismatches, this is to protect the system (and user) from a broken system.
Another thing that is an issue is when you make statements that you have no evidence for such as BSD has low latency, which also points to a lack of understanding of latency and jitter, hopefully you followed the link I provided to an explanation of latency within the context of the Linuxcnc ecosystem.
The thing that hurts the forum is that "member status" is based on the amount of posts. So when you give advice that is wrong or similar it is more hurtful than a recently joined member.
This is not a preseason issue, tho I have made some, I hope offensive remarks regarding yourself, but rather an issue that affects the quality of information that is given in the forum.
Yes I understand we are not born knowing everything, and the more you learn the less you tend to realise you know. Sometimes I am cagey about making sweeping claims, as I know Andy is aware of something that refutes what I said if it was made as a sweeping claim. And I'm thankful for that, I learn a little bit more. We all get corrected no one is special.
So what I'm trying to convey is if you sit back, observe, read and either make mental notes or notes in a notebook or similar and refer to them when answering you will become a member who's post have value. If not you will be seen as just a nuisance.
