I would suggest that we do far more than any other site to respect copyright. For example we spent a considerable amount of time discussing, developing, and implementing a whole new system to add custom text on download sections for titles like your own. The other main download site that hosts Buzzsaw+ has never offered this. We have rights to host Zenobi titles because we care about developers and add custom text for them too.
There are many sites out there that have 1000s of titles for loads of systems, make a fortune from advertising and don't give a monkeys about copyright. Do we all get together and try and close these down? Where are the mass protests?
Regarding Spectacular 5.3 (out of interest version 8 was released in 2012, and I don't believe there has been any active development of the Windows version since this time) on it's own with the license in the installer is fine to paste here. The development environment just needs to add a text file with the license, and a copy of it in their documents.
We argue about copyright every few years (we seem to be in a forever loop, and this always holds us back), and ignore the awful stuff the rest of the internet is doing. I'm not even going to mention the Vega+ and the amount of money they took from the community and never paid to copyright owners or donated the promised sums to charity
We have no advertising, no commercial interest and don't actively request donations (this may change in the future), and don't charge for access to the site. We just want the Spectrum to survive for generations to come.
Sorry for the rant.
