It's Business.
Although what current noteholders/bondholders have done in the past may seem, and it is, a bad thing to KRY/CRYXF shareholders - it really is just business. If this were happening to a friend's investment and they related it, I think most would respond, with a, "that's business," for the most part. In business they are trying to protect their investment. Lenders want their money back. Anyone lending money wants their money back. However, when it personally happens, it's all different.
These guys, the current bondholders/noteholders were saviors when they provided liquidity. Now they are hostile ogres. Don't think the prospective investors don't see how KRY has transformed current bondholders. Might make for some tough negotiations. Prospective investors... possible future ogres.
This will be interesting.
