Lol. Carpenters and framers use Dewalt, Milwaukee, Makita, Metabo, and Bosch. If you showed up with a truck full of Festool, we would assume you have more money than sense. I'd expect to see a bunch of Festool in a fine woodworker's shop over a job site.
Aah, my experience is in America. Yes, I can see festool being much more common in Germany, and possibly not as ridiculously overpriced as it is over here.
I get if people buy their tracksaw or similar but their drills do look like toys. On the other hand if you're already invested into their batteries and you then also need a drill maybe it makes sense to go with the same brand.
Most contractors I know use Hiltis and that's a lot more expensive than Festool. But there's a sayinh that I heard once: Buy contractor grade tools, never buy contractor grade consumables
