They just saw a large market of 3rd party bulbs emerging and saw potential profits for themselves, that's the most likely explanation with the available information. If anyone has financial details to back up claims of "need" for such a move by Philips, please provide them. Philips has been investigated and fined for antitrust violations repeatedly. They don't really deserve benefits of doubt regarding predatory/unfair business practices without need at this point.
