Another sad news :( Thanks for all the years and efforts to provide us price updates!
It seems that a lot of things changes here quickly – it's sad that there is no proper reaction from GOG staff.
I don't know the whole story of the thread. I can see your OP, however I mainly associate the thread with posts of muntdefems and immi101 (I guess they used MaGog data, even if muntdefems was the person, who showed me how to use GOG API to grab regional prices:). I guess I'll never provide such an accurate information here, but I'd like to continue this exact thread with base price updates from time to time, as I've already done above – are you ok with that?
