These days, closed source is also closed formats. And with cloudshit tie-ins, sometimes even means you never even see your data. It's just <hands waving> in the cloud.
For example, the sooner you migrated from Eagle after the Autodesk acquisition to KiCAD, the better. Sure, KiCAD was less polished, but your data and way you work was completely open. If you stayed with Eagle, well, you bent over and took it.
