Excellent analysis, Task!!
I have a doubt, regarding the "VeniceAI" privacy approach: do they avoid the prompts only to be stored on their servers (so the precise part of the interaction with an AI model that can reveal the user's interests, his spelling, specific personal expressions, etc. and link them to his identity if his IP address is findable), or do they discard even "VeniceAI"'s answers to those prompts?
The first option seems to be the most fertile one, as the models go on learning through the iterations and interactions with human beings (and bots) directing questions to them, while at the same time getting rid of most of the privacy sensitive metadata.
