I bet the conservative Justices do. Seila and the DOJ agree the CFPB in its current structure is unconstituitional since the CFPB can only be fired for-cause and is appointed for a full 5 years, theoretically outlasting a president's term.
Also, the CFPB is funded via the Federal Reserve.
There is one director of an agency in the executive branch who doesn't need to answer to the President theoretically over a full 4 year term, and obtains funding independently through the Federal Reserve. There is no multi-director commission filled by directors from both parties to mitigate single director overreach.
Conservative Justices may see it as an afront to separation of powers/checks and balances.
As for the remedy, who knows ...
