Hi CerberusC,
Seems that we agree to disagree 
I wish i would have the time to answer all the points. But with this wall of text i can just grab a few important points.
Thatâs wrong. You have full access and can modify the source code of Unreal in any way you want. For a fact, thatâs the definition of open source.
On the contrary, the so called open source GPL license from the FOSS arsenal is one of the most limiting licenses around. Where is my freedom as a developer to add the code that i really need? In Unreal you can happily add any proprietary code you want. The trouble starts when you try to add so called free code under an open source license. GPL is imho a nasty license. For a fact: The source code of Unreal is more free than the Blender GPL code.

Secondly, the free version of Unity is limited both in licensing and features, something that donât happen with Blender and with that free
version you canât access the source code so⌠not the same again.[/quote]
I still disagree. You can access the BASE version of Blender for free as you can access the BASE version of Unity for free. Blender as it is now is limited in feature set as Unity Free is limited in feature set. You can do everything with both. You donât have to buy anything for both. But in Blender you have to buy the cloud and the addons at Blender Market to get access to the rest. And in Unity you have the asset store. There is imho absolutely no difference.
[quote=]Now regarding the secon paywall, the paid addons⌠yes⌠you may want an specific tool that suits your specific needs, but that specific
tool is not done by the Blender Foundation or by the Blender team at
all, this specific tool is done by a guy in his home, or by a studio in
their offices, and they may choose to release it for free or not, it is
their decission, so you may argue with them about this, or you may try
to tell THEM to release it for free, but don´t mix this with Blender or
BF itself.[/quote]
Thatâs wrong. The Blender Market has a clause that so and so many per cent of the sold addons goes into Blender Development. Blender Market and BF are directly connected. And this means you will not see the features of those addons any soon in Blender trunk. BF will for sure not want to loose the money they generate here.
Thatâs wrong. The GPL license doesnât forbit monetizing source code. Guess what the addons at the blender market are doing. Those addons are under GPL. It would be a simple decision to hide the source code from the public. And give it just away at request and at customers that paid money for the product before.
They could also start to sell addons instead of giving them away for free. And they do, with the cloud subscription. Here we are again at the pay to win business model.

Finally, please, can you name those addons that you think are completely fundamental to have a full toolset of production ready features inside
Blender[/quote]
The tree addon for example. Or the muscle system. Or ⌠what about all of them ? 
Then let me repeat it: Blender is business nowadays, not longer non commercial. And i dislike this direction. Thatâs all. And i simply hope that Blender doesnât walk too much into this direction.
Kind regards
