I used Finale for years before switching to Sibelius about 13 years ago. I found Sibelius much easier to use, but I'm surprised that there aren't enough unmovable legacy Finale users to warrant continual maintenance of the product.
I'm in that camp. I've been using Finale since version 1. I tried Sibelius around the time you changed and it didn't quite but right with my use cases. I have to imagine that there are many like me that have years of muscle memory with the features (not to mention years of scores in the file format) who use it for to avoid having to worry about me software when they'd rather be focused on their music.
Of course... that's a business focused on casually milking an annuity... Not something that's growing. I guess not with it for the people that bought the company a few years ago.
Finally... Wonder what's happening with those Garritan sound libraries I've invested in....
Exactly, years of muscle memory and files. If I was involuntarily forced off of Sibelius at this point, I would be rather annoyed. I'm not even sure what I would do. Last time I tried it, Dorico did not support everything I needed to do, even if I wanted to use it.
