Oh 100% same here. I fire up the blender all the time. I've used the software since the mid-90s back when they first started porting it to x86 based platforms. Back when there was the shareware versions. So I am 100% on the same page as you with promoting Etc. I really love these softwares. And would love to see them get more love.
The main thing I was voicing was that the fediverse is already a small slice of the community. And then further restricting it on top of that is going to make it an even smaller slice of a smaller slice. So I absolutely like the concept of the initiative overall.
