Some people knew of this trade and some didn't, for whatever reason the power brokers of the trade decided. Kyeie was allowrd to know of the trade and obviously approved as he passed on a multi-million dollar trade clause to come to Boston.
It wasn't consulted with IT, which is Danny's perogative, and the trade went down. That's business. Is it cold hearted?
Yeah, maybe. But this is a business and players and teams need to realize this rather than playing the victim role after aonething doesn't go their way.
