Thankfully, Azath, that can never happen due to Blender being Open Source (technically everyone owns it already).

Can't happen to ArmorPaint, GIMP, or InkScape either, for exactly the same reason

That's the power of the Open Source: It cannot be beaten as a business model because at the end of the day, the "Free and Open" business model is always going to win over the "Expensive and Closed" alternative. A perfect example of how dramatically things have shifted over the years would be to compare Lightwave to Blender. There was a time when Lightwave was the be all and end all in 3D graphics, it was even used to churn-out Star-Trek back in the day.

Forward to today and who would have thought that more people would know about and be using Blender, than Lightwave. I love Lightwave, Cinema 4D, and ZBrush. Fact is though, I cashed-in my licences for all of those programs due to Blender allowing me to do all of that in one program, and that was a long time ago now, I simply did not need them any more.

So yeah, don't worry about Adobe or Autodesk sucking-up Blender, it can never happen (thankfully).
