Advocate Dali Mpofu who was the CEO of the SABC between 2005 and 2009, trashed the SABC in front of the Compliance and Complaints Committee of South Africa's broadcasting regulator during a late Friday public hearing.
Dali Mpofu said "other neutral broadcasters, not slaves to the ruling party, have aired the advert".
Dali Mpofu, a former card-carrying ANC member, was referring to the shocking way in which the SABC banned the Democratic Alliance party's "Ayisafani" TV commercial, followed two weeks later by also banning the Economic Freedom Front (EFF) political party TV commercial just before the upcoming elections.
Dali Mpofu said "his master's voice" - a reference to the ANC stemming from the apartheid -era days when the SABC was a National Party mouth piece - is "muzzling" freedom of speech in South Africa.
"The fear expressed by the SABC [of banning political TV adverts' amounts to censorship, it is a citizen's right to choose or reject," Dali Mpofu told the Independent Communications Authority of South Africa (Icasa).
