Adobe burned all bridges with their customers when they introduced CreativeCloud, that universally hated DRM app that randomly maxes out your CPU.
Also, before, companies, schools, and universities could purchase a few perpetual licenses and use those for teaching. Now, they would need to spend much more on person-bound license rentals.
So I'd say XD never had a chance because it launched after the customers left.
I'm still being held hostage by them to access my old files, but for every new project, I go out of my way to avoid using any Adobe-specific file format. If others do the same, then XDs only chance is a truly open file format that other apps can also use.
EDIT: If I remember correctly, I released my first self-developed plug-in for Photoshop 5 around 1999. So I've been using Adobe products for a long time. Back then, plugins for hobbyist power users were a big market. Nowadays, that market is dead. All the hobbyists went to Gimp and Inkscape.
Similarly, the Substance3D communities became a ghost town more or less overnight when Adobe purchased the company and then removed Indie pricing. It went from $99 one-time on Steam to $49/month (min 12 months, so $588 annually) as part of Creative Cloud. Suddenly, Marmoset - their long-term competitor - became very attractive at a one-time $119 for students for a perpetual license. I also lost access to my old files there.
Can anybody recommend an Audition alternative that does not require a monthly subscription to use?
For music production, I've been using Studio One [3] for the last couple years, and it's truly the mosf straightforward and beautiful DAW I've ever used. Though, it's not free and open source, which is a downside for me. It's one of the few proprietary software I care to own.
Zrythm [4], however, has been catching my eye lately, and I'm looking forward to it maturing to the point where I can finally move to a FOSS DAW.
