OS4 isn't there because it's still on sale same as OS3.9 isn't on there, everything else that's there is because other than downloading them from sites like mine from the net there is not other way for folk to easily (if at all) purchase them anymore... 
As I've said anyone can easily find every piece of Amiga software on the net, just reckon it's way past the time to stop pretending that this is not the case and put an end to all the nonsense that this is somehow harming sales somewhere and pretending that this doesn't happen...
I've already said here that you can get hold of KS ROMS & Some Workbench versions by purchasing Cloanto's Amiga Forever but what about folk who have no use for Amiga Forever why should they have to pay over the odds for something when all they need is a working copy of some Workbench disks...
At the end of the day I don't make a single penny from my site in fact it costs me money to run the thing, so what the fuss is all about I really don't know...
People here used to be crazy on the attack when they found any copyright infringement (which like it or not is what you are doing) Many of them have left or don't attack as much anymore.
Ebay stuff was especially bad, they would email ebay if a commodore logo, or disc filled with copyrighted stuff was for sale.
Like I said though, offering copyrighted material for download, even if you don't make money, and even if you don't make money on it.
I bought Amiga Forever several times for a variety of reasons, and I don't really care what you do with your site, but they could concievably come after you, they have before.
