Large companies have become money sucking dinosaurs. Much like IBM, Oracle, Microsoft of the 90s. Can't wait to see some competition eating them.
We let them get too big. Nowadays they just buy the competition in the cradle, even if just to drive nascent products into the ground.
There is a always a chance that the next generation gets hooked on to a different platform. That phase where an emerging competition is eating the incumbent's lunch is the best time to be there.
