Telegram has a long history of obfuscation when it comes to court orders. In Brazil, they simply ignored previous court orders until they were banned. They played a similar trick in Germany too, and backed down after heavy fines: https://www.dw.com/en/germany-takes-on-telegram-to-fight-ext...
So, I wouldn't take anything they say at face value. It's not only about giving out the information they have on these individuals, it's also about shutting down other similar groups according to the court order. I'm not a free speech absolutist, I think that no platform should harbor Nazism and death threats, particularly after they have already resulted in murder. If they fundamentally cannot comply with this, then they should be banned indeed.
