There is nothing wrong with saying that you think all old Amiga software should be freely downloadable as long as you are happy to say within the law.
I would say that sites like back to roots have the same view and that’s why they as the owners of Amiga titles for permission to distribute them from their web site.
There has also been a trend for companies to make older versions of their games available for free download from their web site to help advertise their latest releases.
Rockstar games release free release of an undated version of GTA1 from their web site is a good example of this. A number of Amiga games have been given away for free in the same way from their owner’s websites.
