Esto es lo que dice el desarrollador:
First, I would like to point out that I have been very happy with GOG. They have been very helpful and replying super fast. As a developer I have had nothing to complain about. I did indeed experience slow replies, but only related to the cancellation of my contract.
After releasing on GOG, I started getting complains and even refund requests because of missing achievements, workshop/mod support, cloud save and so on.
Adding these GOG features to SC is indeed possible, but it would require a playerbase to cover the expenses. This has unfortunately not been the case.
Combined with the added workload of supporting 2 platforms instead of 1, I decided that my players would be left off better with me focusing entirely on Steam.
I want to make it clear that I believe GOG is awesome and the staff has been doing a fantastic job.
I'm going to make an official announcement on the SC forums once everything is in order.
I will provide a free Steam key for all GOG users who has purchased Startup Company. I will also offer a DRM-free version on request for all mayor releases.
Startup Company is still very actively in development and I'm working around the clock pushing out new content. I am not abandoning the game and will never do.
I hope this clear things out
