Appsumo LTD's Newest Plan "Legacy Free" explanation

Can someone help me understand what they changed for Appsumo LTD users? From the email describing “Legacy Free” they mentioned that we still have unlimited automations and runs, but if it involves AI it’s a credit based feature now, even if we use our own API Key (BYOK).

Does that mean if we have a step that involves our OpenAI connection, we can only run it 200x per month without paying for more? I understand the credits to use AP’s AI, but why charge to use our piece that uses our API, that costs them nothing? Or, am I getting something wrong?

Please help, I responded to the email, but I didn’t get a response back on my question.

Thanks!
