I totally agree on these things:
1. Updates take forever to get through their system.
2. Everything is encrypted (DRM) and that right there means you lose control
When I fly, because I buy NOTHING from the market place I (not Asobo/MSFS) decide what loads when I start the sim. What I load is the airport I am flying from, the airport I am flying to and the alternate. Everything else is stock. I only load the airplane and livery I will fly. That's it.
The simple way is really Addon Linker, which I also use for the flight from airport to airport, the important things are still around and otherwise everything is in stock as you write.
But since I'm on the GSX discussion, I'll mention the problem, which really lies in the fact that if I have to use it also at the airport, which I purchased unfortunately via the Marketplace / I will never make such a mistake again because of file encryption, purchased elsewhere without encryption / unfortunately, this is not an option adjust the airport using GSX ini and that's enough for me.
I understand that the creator of GSX didn't do much with it because this is Asobo's policy, to make things more complicated than they can be. And I'm not talking about CTD crashes just when GSX was released, it was unnecessarily smeared in the introduction of the release even though it was not to blame and it is an important part of the whole MSFS, which embeds the reality of the entire simulator.
