Look at most IT acquisitions and sweep away the forward looking BS.
The companies acquiring the company generally just want to take a product that they can sit on, screw existing customers and jack up prices.
HP thought they could do that with autonomy, but autonomy were already riding the screw the customer bus hard. HP was desperate for a big name acquisition to show they weren’t past it. HP thought they could fly through due diligence, pay top dollar and make the board look like they weren’t a ink company with a dying printer/PC/server market.
