While not dispositive of your idea, I think some portion of people using their personal accounts is because we collectively lack good feedback loops on the effectiveness of “AI addons” like RAG. The corporate accounts can be legitimately less useful than a “stock” account because the AI team integrates everything under the sun to show value, but the integrations become a net negative.

Ie ones that index entire company wikis. It ends up regurgitating rejected or not implemented RFCs, or docs from someone’s personal workflow that requires setting up a bunch of stuff locally to work, or etc.

A lot of tasks are not dependent on internal documentation, and it just ends up polluting the context with irrelevant, outdated or just wrong information.
