You're right, minimal techno is not the most popular form of techno right now. That's not a new thing that happened in this decade though. Techno has been going through trends of being faster and more maximalist vs slower and minimalist since it began. I'm sorry that you're struggling to find minimal techno nights to your liking, I'm sure there are some out there and I'm sure the trend will come back around. But the techno of my generation is not all EDM or trap influenced so I know you're talking out your ass. You may have been to many techno events in your life, but what you're saying here just proves you're out of the loop like many nostalgic oldheads. So maybe just take a step back and consider that you may have lost touch with the underground. You certainly have if you think drumcode is an underground reference these days.
If I have to go to a club in new york or berlin to hear music it's not culturally relevant. The stuff you linked gets zero play at festivals.
Edit: Festivals have never been the beating heart of the techno scene my friend. I'm sorry to break it to you. And again, I've been to good festivals which do play this stuff - you clearly don't know where to go and you're taking it out on my generation when its on YOU.
