I too am a long-time Sibelius user (actually on and off since the 1980s with the Finns on Acorn); and am still very aware of its many strengths (features, plug-ins, huge user community); and weaknesses (App Manager, support, robustness): it appears as though there is a lot of scope for Avid to change with its many loyal customers’ needs…
Dorico is a game-changer, though, and sets new standards. It’s the future. So I’d be sorry to see anyone turn away from it because the protection system is not 100% convenient for them.
