Super pessimistic point of view. Why do you think these are all in danger? These are things that people and more importantly enterprises use. Why would IBM ruin that?
Sure rationally the products should be a success, that's why IBM bought them. But GloboMegaCorps have a consistent record of acquiring great products then running them into the ground by smothering them with shitty internal policies.
It seems like a fair % of SVers haven't had the pleasure of working for one of these Kafkaesque giants. They operate on dream logic and risk aversion.
Though I dedicated a few years of my life to OpenStack at HP, I sometimes wonder if OpenStack would be healthier if GloboMegaCorps didn't get involved.
