I have know knowledge of this incident. But often corporations don't make sense from the outside because it's really about some hidden state.
E.g., maybe the person who argued for the acquisition left the company, so nobody was around to advocate for it anymore. Or the company's strategy changed, either for sensible reasons or just because there's a new fashion. Or the person in charge of the acquisition is mainly rewarded for buying things, but the people needed to make the integration work are rewarded for something that the acquisition would hinder, so they ignore or sabotage it. Or everybody really meant well, but it was nobody's highest priority, so it just dies a slow death.
