StingingVelvet: GOG tried to make a play for Steam market share and it didn't work out, and they wasted a lot of money doing so. It is what it is.
When exactly was this?
GOG from all I have seen have never taken on Steam in any manner.
GOG just sell DRM-Free games, which is a rather small collection of games compared to what Steam has on offer, and it has never been any other way, certainly for AAA and AA quality games, which in GOG's case are mostly old ones.
Even the Indie games at GOG are a small collection compared to the likes of what Steam and Itch.io have.
Aside from a few exclusives at GOG, there is no point to buying a game at GOG that is also available at Steam or Epic etc, unless you want a DRM-Free version, and in many cases those stores have a DRM-Free Lite version anyway, if more painful to obtain as a good DRM-Free installer type backup.
I love GOG to bits, but if you are serious gamer who cares more about the game, you would buy from whoever has it, and often price isn't even a major factor. I'm not that kind of gamer, and I have such a huge collection of games now, a great number of them free and DRM-Free, such that I can ignore most of what is on offer from Steam and Epic etc. I can certainly do that in the sense, that I will play what I have first before bothering with those stores ... which in my case, is going to be never. In fact I will likely leave this mortal coil before I deal with my backlog.
--------------------------------------------------------
Anyway getting back to the premise of this thread.
Did something change, because GOG have always been the underdog, and certainly from where I am looking, GOG have more games now than ever before, a huge number of them great, if somewhat old.
So I really don't know where the concern by OP and others is. Business as usual from what I can tell.
Game providers are in the habit of making money ... have always been that way. For many that means avoiding GOG in most cases, until it becomes financially beneficial to bother. And some never bother because they either don't like GOG or don't want to support DRM-Free or whatever.
All that said though, if GOG stick to DRM-Free, then eventually they will go the way of the Dodo, unless they can pull a rabbit out of their hat. DRM-Free is certainly not where the world is heading, and GOG have had enough time now to make significant change if there was ever going to be any. But meanwhile things have moved on, and gamers and the gaming industry model are changing, and ownership is going to become less relevant over service and features etc ... sad but true.
