The question is how many users have developed intimate personal relationships and have named their ChatGPT, and how many of them would bounce to a different provider if some line is crossed (of which advertising could be one)?

Anecdata isn't data, but I know several individuals who have and thus are even more unlikely to churn than mere brand loyalty on the level of eg Coca-Cola.

I’m curious how that intimate relationship evolves once ads are in play.

Wait we don’t need to wonder. The chatgpt 5 rollout showed us exactly what happens when the intimate friend changes.
