Evidently there’s some difference to the approach. I’m not familiar with the WinRAR days, but they specifically address that in this video. I don’t know if it being similar to WinRAR is a good thing or bad thing in your book, but maybe you’ll enjoy the video.
I’ve basically agreed with you this whole time, see my initial comment regarding the difference between the previous comtribution model and the new request for purchase:
However we’re drawing different conclusions about the situation. You say it’s misleading and morally wrong to refer to “buying” this software, I say it isn’t and that it’s actually a helpful perceptual change in fostering support from their users.
I don’t really think there’s anything else to say beyond that. If you don’t like how Immich is handling their software, don’t use it.
