Logitech has become dogshit and I've since long started avoiding it. First their mice died like once a year, then they stopped supporting their older hardware which forced you to run like two to three different pieces of software of you wanted to keep its functionality. Haven't looked back since I moved on, they can suffocate on their enshittified nonsense.
You're unreasonable. Getting an installer that installs a fully working game is perfectly fine. Where you store your boxes or files is your problem, GoG won't build a garage for you for your boxes, neither will they send you a data crystal that'll keep your data integrity for a million years.
Stop shitting on great because it's not perfect.
