It's more about companies taking an open platform, co-opting it's userbase with a good solution, and then kill or stagnate the platform in one way or another... Microsoft did something similar with IE back in the day: it was better than Netscape and it quickly dominated, but then they kept adding proprietary hooks (ActiveX etc) and the open web started to stagnate - until Firefox saved the day with a faster, more secure alternative that slowly gained back hard-won market share. I don't think this phenomenon of hurting open platforms is necessarily intentional, perhaps it's a side-effect near-monopoly products in a given space.
