It's nice a high profile project such as Blender speaks about freedom to push back against the "source available" movement. I've always wondered why niche specific software such as Blender doesn't have a ton of industry backing. Any medium sized graphics shop could have a full developer on the payroll for a fraction of the repeated licensing costs of proprietary solutions, that is, someone who works full time on Blen…
It's more likely that the SFX industry has their training done on proprietary software, and shops that don't use the industry standard ones like Maya would have trouble hiring. Plus the after market plugins tend to be commercial in nature and won't want to sell with a GPL licence.
If you have even a modicum of experience with one thing, you can pick the other up in an afternoon and be up to speed within a week.
