Yes, a big corporation with big pockets means more money and stability but it comes at a cost. The cost being whatever you do must at the end of the day feed back into the pockets of your parent company. Twitter used to be a platform too but how many third party applications do you see now? A lot less than what it used to be. What do you think will happen to Oculus applications? Those that are sanctioned by Facebook will thrive and those that aren't will be brutally shut down.
At the end of the day this isn't good or bad. It is really more about long term disruptive technology and its viability outside giant dens like Facebook and Google. Looking around I don't see an ecosystem that can support such things without giant corporate backers and that is definitely not a good thing because at the end of the day the values of our corporate overlords tend to be slightly misaligned with that of the individual.
