You are right, we can not capture a messy and complicated human being. Therefore we tried our best to frame it right with the “Echo“ and disclaimer. We have the fact check sheets to show what is recreated and what the facts are. We also have the shadow section in the fact check sheets to show that these humans were messy, but tried to portray them inside the platform for what they gave to the world, all under the objective to make hard accessible wisdom / philosophy more accessible, as a doorway, that people outgrow us and move from our introduction to primary texts and human teachers.

I think "echo" is a fine word to use, they're hardly calling them "reincarnations".
