Taking away the ability to centrally enforce an opt-out across an organization is a massive red flag.
You can't reasonably expect every individual employee on a Team plan to remember to dig into their personal settings and flip a privacy toggle. For any company dealing with sensitive IP or GDPR-compliant data, this basically makes the Team tier unusable.
Yes. If the privacy control only exists per user, it isn't a control for a team.
Defaults matter more than the blog post. "You can opt out" is not the same product as "the org can actually enforce opt out."
This isn't the case. There's a toggle on https://admin.mistral.ai that allows you to disable training for both Vibe and Console/API for your entire organization, I just checked.
