When the internet threatened newspapers, some of them cut their prices hoping to grow their customer bases. Others raised prices hoping to offset revenue losses due to attrition with increased revenue from loyal customers.
Either situation might have been the most profitable approach.
Ultimately, it played out that those that raised prices kept larger total revenues even though they had fewer customers.
To me, it looks like all the DAWs are taking this view. That some customers will be loyal and will pay the higher prices, but the customers that will leave for open source will not stay or adopt a DAW they must pay for even at 1/2 price or less.
So, as the cost of staying with a high-end private DAW goes up, you can expect that the number of people switching to Ubuntu Studio with their class compliant interfaces to climb.
The high-end studios could also switch to Linux at a large annual savings. One of the big hold-backs is the limited number of companies that license their VSTs for Linux. I have no idea why they don't. Like, why doesn't Cakewalk license the CA-2A for Linux?
As the number of users using Ubuntu Studio grows, the quality will grow too. So will the variety and options of add-ins.
Anyway, I think that the companies are positioning themselves. It might take 10 years, it might take 100, but eventually there will be serious open source alternatives.
