Hmm... I agree with parts of this and disagree with other parts. In my experience "cross-functional collaboration" splits into two distinct components: leadership and information. Anecdotal, but when leadership is split into too many people at the same level who are each in charge of a domain (that requires heavy interaction with the other domains), nothing gets accomplished—analysis paralysis and politics takes over. You absolutely need one specific person as the final decision maker. They should carefully consider all input from various sources and then make a final decision in a timely fashion. If it turns out to be the wrong path, that's fine, just reverse course quickly as well.

On the other hand, information silos are absolutely horrible. The most effective companies I've worked at have always had tons of information freely available to all employees. Unless there are privacy, cybersecurity, antitrust, or similar risks involved, every employee should have access to all information across all teams. It should be easily searchable as well. There are certainly exceptions—Apple seems to function well despite all the secrecy. But most companies aren't Apple, and I don't think it's generally a good strategy.
