"Who knows?" Playing the FUD game?
Acer never owned anything Amiga. The copyrights and trademarks can easily be looked up, while the patents expired before Acer even bought Gateway.
No FUD. Nothing I have seen convince me Cloanto own the ROMs. Trademark on "Amiga" got nothing to do with that.
You are right in that this has nothing to do with trademarks. Copyright assignments can be researched on this US Government site (here a sample output for "Cloanto"):

I think Gateway, and then Acer owns it, but who knows.
I used https://aminet.net/package/util/misc/GrabKickDisk to grab ROMs from my Amigas. But you can just as well grab them from random internet site, check the checksum and be happy and guilt free about it.
