There's no problem with commercial / locked systems being used on the 
ham bands, as long as the mode itself is open, properly specified or 
even documented (take PSK31, Joe's WSPR, or Stewart's WOLF for example); 
not plagued by software patents (which prevents it from being 
implemented by others, for example "D-Star" which is based on a 
proprietary codec, which imho makes it uncompatible with amateur radio).

Fortunately others have taken a deep dive into Opera and successfully 
reverse-engineered it, which -ideally- should not have been necessary if 
the mode was properly documented by its creator.

The problem I had -with the original Opera software- was that when 
trying to download it, my browser was immediately hijacked by commercial 
ads... trying to sell me all kinds of stuff but not a simple 
(stupid-javascript-less) file link to O-P-E-R-A ... been there, won't 
try again.

73,
  Wolf .
