tldr is that you can hide the button that asks for payment and it says “purchase immich” instead of “purchase liscence”
Why do you think you aren’t really buying it? Is it because they allow you to run it without paying money for it?
I don’t think the definition of “purchasing” software should be defined by whether you can run the service without paying or not. I think it’s best defined as paying money for something that you like and want to exchange value for. In my book that’s nothing near a dark pattern, as I can’t imagine anyone being confused by it, let alone mistakenly believing there is missing features that they won’t get until they buy.
Buying confers ownership of something even if it’s just a legal agreement like a software license. No ownership over immich is being conferred, nothing is being conveyed to anyone so it’s incorrect to term it a purchase, much less a purchase of immich.
Ownership is being conferred by purchasing immich, that’s what the product key codes they’ve started using indicate.
That is the fundamemental change in the way they are offering Immich: if you pay, you are provided with proof of ownership (product key). If you don’t, you are using it as a part of an indefinent trial period.
No, no ownership is being conferred except to a number, the supporters club key let’s call it. That is what you are buying, it’s like an NFT. And just like NFTs it’s being marketed as though you are purchasing the work itself which you absolutely are not doing. You are paying for the right to say you paid.
If you don’t pay you are in exactly the same state as if you paid regarding your license to use the software, it’s licensed to you under the terms of the agplv3. If they were selling a support contract that would be fine too, but again, no, you get no extra support over what anyone posting a issue on the tracker will get. Even if it were a support contract then it should be made clear that is what you buy.
