@nullnull You’re misinterpreting what I said, and this poll is therefore based on a wrong premise.
Of course RawTherapee can be your personal replacement for ACR, I never said it couldn’t. However, if you try out RawTherapee and expect something that works very similar to ACR, you can and probably will be disappointed. My statement came from a design perspective: nobody sat down and thought “Let’s make something that can replace ACR”. This is a very important distinction.
Edit: To further support this notion, some of the developers of RT don’t even own Adobe products or have only used them a long time ago. So nothing is designed only because our ‘competitors’ have the same functionality.
As a matter of fact, I turned away from Lightroom myself and started using RawTherapee to process my photos years ago.
