MaraST78: #1 - Solution was already posted in another thread.
What solution? Are you talking about the MALLOC_CHECK_=0 glibc workaround that I have used since 2008, when Enemy Territory: Quake Wars would not run without it? Are you soliciting credit for a ubiquitous workaround that has been around since glibc 2.0?
See 'man malloc', comments section, last paragraph.
MaraST78: #2 - One never owns anything in the world of proprietary software. Fact that Steam is another piece of software one needs to run some game he has license for is true, but generally same thing - proprietary software is never owned at all.
Will you not agree that when you are condemned to closed source software, closed source software without digital restrictions management is preferable to closed source software with digital restrictions management?
Digital restrictions management is a disproportionate step above closed software; from a privacy and security vantage point, software that need not "phone home" prior to running is better than software that does "phone home".
In the case of Frictional Games, they have released the source code to their HPL1 engine. See:

MaraST78: #3 - People here at GOG seem to somewhat romantize things. If you think that GOG is here to be your friend forever or something, he, no. They are here for profit, simple. They know that getting profit in their case means DRM-free stuff etc, after all that's where it all started. As long as it's profitable, it will be like that.
If you look at GOG library of DOS games e.g., there still is a big number of those that have only Windows installer.
Frankly, it doesn't make any sense. If the Windows version is done, Linux version is done too really.
A Linux version is not "done too really" if the Windows client is. Porting an engine from DirectX to OpenGL is not a trivial chore. Your statement above only holds true for Windows games with an OpenGL renderer backgend.
MaraST78: Existence of money means GOG can be here to make profit, which means Windows versions of stuff first, all else later. And only after Galaxy or any other POS gets in my way w/o ability toget rid of it, I'm done, as usual.
But since W10 is an utter mess of beta quality, yet being a spyware itself, those millions of those who "upgraded" will be sorry for killing their old W7/8.1 licenses. Maybe Windows versions will not be a priority in a few years. ;)
I find your point of view unnecessarily cynical and gloomy. If GOG were purely motivated by profit, they would have allowed programs with DRM on their store - they are turning down some big money by denying DRM encumbered games. However, all software on GOG is available without digital restrictions management and GOG Galaxy is an optional addition; it will not be required to run any games as that would in essence be digital restrictions management.
