Why should anyone contribute their time, content, thoughts, and often money into a company's platform when the company doesn't care about anything but protecting it's bottom line, and then severing you from and taking control of your already spent time, content, thoughts, and often money? The other big problem is that Reddit hides the fact that it takes every step possible to limit users in order to protect it's bottom line... That's textbook bad business.
