I mean… you know they sold out to Aussie-Adobe like 4 years ago right?
They are currently strip-mining the code so they can learn how to write an application that isn’t an instagram filter tacked onto MS paint… I just made that last part up, hopefully they do something good… but I assume they acquired Serif for the sake of IP protection and not because they were hoping to develop it further. I haven’t seen anything innovative happen for the last few years at least.
