I agree with many of your points. I am reminded of the well know Ted Talk about Flag design. A flag should be both recognizable but also easily replicable. The pentagram logo is recognizable but is hard for a normal person to replicate. This logo is unique enough but is easy to reproduce.
Threads Fediverse logo is easy visually and can be reproduced in color or black and white but I don't like like it. Mostly an aesthetic thing.
