(Laughable) Answers to these questions have been given in here: https://bitcointalksearch.org/topic/m.60518076. To me, the TLDR is that you can't trust a single line of code coming from these people.
I'm not defending Kruw, but that, ser is such an irresponsible statement. You probably can't trust a single of code from Kruw's contributions/work in closed source project/proprietary software - IF he did any of that. But in Wasabi I believe all code/contributions from all developers are Open Source, no?
It's understandable that people ask questions because there's doubt, but let's stick with the facts and avoid mud-slinging.
