They need to absorb things so their sales team can say "oh we have X feature" regardless of its actual implementability and just leave it to the consultants to struggle and somehow implement a half baked solution that doesn't work in the end.
Oh but that's how they make money also. More products, more features, more crappy integrations = more service contracts, more consulting work, etc.
All a huge scam that enterprises are forced into because they don't want to be "left behind in the digital economy."
