I hear you on the support side. I used to work for a company that used a product that was bought by IBM. Before that, you could pick up the phone and talk to the lead developer. After, you opened a support ticket online and waited 24-48 hours for a response from someone in Costa Rica or India. Now I work at IBM with this same product, and even I as an employee who supports the product, even I have to go through the same Level 1 tech support crap.

However, the cash injection made the core product worlds better, and it was good to begin with. Support got worse, the product got better. It's almost an even balance.
