Is there any way out of this madness?

The problem is that any sector that gets successful in exports is immediately weaponized by Kremlin, either for bullying other countries (Gazprom, Rosatom) or simply for racket (Nginx).

If that goes away, and I think it's entirely doable in a year or so, Russia has plenty of things to be proud of - Rosatom, Gazprom, massive and highly competitive IT industry, new prospective hydrogen energy projects and many more.
