I agree mostly. The Blender Foundation's seems to listen better to studios nowadays: the LTS (Long Term Support) initiative is great, allowing studios to work on long-term projects while staying in one stable version that is bug fixed for two years. The current version 2.83 already received 5(!) LTS updates since it was released last June. I noticed a marked improved stability since release 1 (and Blender is on the whole very stable running as it is).
And version 2.9 is about to be released (next week) with a quite long list of interesting new features and improved edit mode performance, but also nice little GUI improvements across the board. The usability of the outliner, for example, is improved once again.
One thing I have noticed over the past few years is the DELUGE of add-ons for Blender. It is intimidating and impressive at the same time. I see ex-Modo users create addons to bring Modo functionality to Blender. I see ex-Max users create addons to add features they had in Max. The community is hard to beat.
Anyway. A c4d to Blender plugin would be nice to have. Are you aware of the copy and paste addon/plugin that allows for copy and pasting of geometry between various apps?

I've used it at work for seamless and quick switching between C4D, Modo, and Blender while working on projects (before Covid, that is).
At the risk of repeating myself, in my mind licensing is the major hurdle right now for MAXON. Secondary hurdle is the rather slow development of C4D in the past five up to ten years. It is lagging behind and relying too much on third-party developers to fix the gaps, which rubs more salt in the financial wound, so to speak. Hopefully with R23/S23 development will have picked up.
