How did you qualify for the 50K status? Through the regular SQx means or was it granted/gifted somehow?
The only clawback I'm aware of pertaining to credit cards is with the 30k points earned promo via card spend, where the terms and conditions say that they reserve the right to clawback status if you cancel your credit card. However, that's for 2023 status, so I doubt they'd be working through that now
