I only know 2 parallels, one is Blender, which is really gaining traction. Lots of huge sponsorships, increasing adoption. Thats the open source road.
In Adobeland, slowly Affinity Photo and Designer are gaining foothold. I don’t think at this point it is any danger to Adobe Photoshop and Illustrator. But a Affinity version 2 might be pushing the monopoly back.
After Effects also has a competitor with Cavalry now. Beta is out now.
Adobe is the Autodesk or 2D world. I’ve heard they don’t even have Dev teams in the US anymore, for the most part they have teams in India. Profit maximisation at its worst, since now they no longer deliver meaningful updates to their software. I haven’t had a significant update for Premiere/After Effects that made any sense in at least half a decade. If you go into reddit/r/editors you’ll see it’s full of people working their way out of Premiere, which is garbage software.
