Whenever an investment company buys out a company, they screw the customers to milk them up for maximum profit of their shareholders. Countless good, innovative tech companies have been ruined in that way in the past decades. People who havent contributed to building anything the company has built, move in to milk the customers/users for their own gain.
The best reaction to this kind of skulduggery would be to remember the investment company's name, remember the name of its CEO, and stay away from whatever they are involved in.
Im also going to look for alternatives to cpanel. Virtualmin seems an alternative, its GPL version is pretty sufficient, their pro licensing is reasonable, they are still owned by their developers. Even more, its possible to do things like High Availability setups which are not possible with cpanel at all.
