Czech oral history (likewise the oral history applied in others so called post communist countries) did not experience that building period in 1960s and 1970s, partly at the beginning in 1980s, where in the world is spoken about social movement more than a method. With knowledge of the thing I can say that this development was in its beginning probably necessary and well- founded.
Understandable (in its beginning) was also some political activism. In 1970s and 1980s in Czech Republic (similarly in other countries of so called socialist block) was OH absolutely unknown.
History and historians did not know about it. Isolate attempts to invite witnesses for scientific project ended without accomplishment (ideological task, guiltlessness of method, imperfect technique, etc.).
Hypothetically, if the OH had been discovered earlier for Czech historians, it could have acted positive and surely combative activist role (as A. Freund.
P. Thomson and many others speak about it) like in other authoritative regimes.
Twenty-one years is enough to make a man grow up as well is sufficient time for young democracy. Sufficient time to start thinking about its past without prejudice and in historical context through the social scientists, so also the historians.
For Czech oral history it is certainly a big challenge.
