Br Abdulwahhab is correct that if a person is ma'zoor and doesn't disclose this and just asks a general question 'can i read read Salah without re-doing wudhu'? obviously the general answer would be no, it is haraam. but there is a exception if the said person explains his position to the 'Ulama well, but that would entail him disclosing his problems. Similarly in the Hanafi Madh-hab - Madh-hab hopping is not allowed and that is the general ruling and only exceptions can change this ruling depending on person and situation. The questioner (in the fatwa) if he was Hanafi in the first place didn't have any valid reason according to the Hanafi Madh-hab to change his Madh-hab or didn't disclose any other reasons that would allow the Rukhsah. Simple.
No need to get alarmed.
