It's more like finding the subscription for a CAD program too expensive, and swapping to something more primitive instead. If that offends you, I think you gotta have a long hard look in a mirror some time.
FastRawViewer, DxO, Affinity, Darktable, Capture One. Those are just the ones I personally have installed. There's also RawTherapee, a number of camera OEM-specific tools, and more.
If Capture One still is like this, I wouldn't really be surprised if there's truth to the other comment here claiming that their current owners are trying to offload them.
And I'm sure this will all change when the new vulture capital fund that snaps it up tries to extract every last microcent of "value" from the brand.
I should also note I jumped ship to DxO as soon as C1 started going down the subscription hole. And frankly, I'm kind of glad they're struggling. I guess they thought they were going to replicate Adobe's "success" with subscriptions without first being a near-monopoly.
