I don't really care about the details: I do not trust anyone who works with cryptocurrency. I don't care how close you were with them, I simply do not trust them and I will not work with them. I will support the denouncement their work. Cryptocurrency is a disease, and I hold those who proliferate it personally responsible.
I do, however, credit the author for denouncing it even after being involved with something similar in the past. That's called personal growth. I won't hold a grudge against your colleagues if they choose a similar path for themselves.
