The mergers are completely focused around monopolization, which is what happens when "over-regulated" companies are not regulated.
In the electronic CAD software space the goal is to absolutely milk customers for every last penny, because changing vendors is fairly painful.
The last thing you want to do is to allow a lower cost alternative, or any alternative, to exist otherwise you can't keep raising the license costs every year for no reason.
So naturally, you buy the competitors and do the absolute bare minimum of maintenance to keep them alive those former products alive, all the while using them as a list of victims to receive never ending calls about upgrading to the more expensive products. Also, eventually you kill those products because you allow existing customers to have them but don't allow new customers.
This is critically important now that there's virtually no way to get out of monthly/yearly licensing fees as you won't just go without upgrades, the software will stop working. So being able to raise prices year after year is easy money.
I guarantee there is no upside to this for VMWARE customers. Well, unless they like paying more for the same thing, then there's plenty of upside.
