You are not paying 12 euro for something you don't need, because that 12 euros is the total charge, including what you do need. Then take a look at what Adobe charges for single apps other than Lightroom...
Thanks for all the responses. Maybe I should clarify something. I am a hobby photographer and not a semi-amateur or professional photographer. I was looking for an alternative to Picassa in 2010, I got into LR 3, and in 2016 I bought LR 6. All this for about 200 euros. My usage is ad hoc and sometimes times not. Costing in the end 1,20 euro per month. If there had been an LR 10, I would have bought it and until now it would have been 2.5 euros per month. A price I was willing to pay. If I had payed 12 euro from the beginning I would have paid 1440 euro. And if it would be my work, a price well spend.
And still LR 6 suits me fine, but now the map module and the face recognition no longer work, and LR sometimes stops working. I don't need Photoshop at all. So buying LR separately was a great solution.
I also hoped Adobe would read these fora.
Hence this post and questions. Because now I unfortunately have to look for alternative and I can't find it yet.
