I think they have a chance. I know a couple of professional photographers. One uses Capture One and only for tethering support. The other an ancient copy of Lightroom that was a one time purchase and use that for persistent contract work for one of the larger advertising companies in London. If the price is right and it's good enough, they are probably going to do fine.
I'm an amateur and I want to get off LR because I hate giving Adobe money every month and the damn thing is a fat pig compared to Photomator. Photomator is missing decent dehaze and because I have a shitty little DX mirrorless, I need the denoise and it's not as good as LR is.
