One notable example is J.D. Salinger, though more a writer than a speaker, who gave public interviews early in his career but later insisted on total privacy and exclusion from public record. More aligned with public speaking:
Thomas Pynchon has avoided public appearances and has repeatedly declined participation in the public or archival record beyond his published work.
In politics, Dick Cheney and others in government have invoked executive privilege or classification to keep parts of their public duties out of the official record—though not always successfully.
Dave Chappelle, during live performances, has required audiences to lock away phones to prevent recordings, signalling a desire for ephemeral speech not archived or widely distributed.
In a more everyday sense, many academics or experts who give talks at conferences will request their sessions not be recorded or shared, often to avoid being quoted out of context or to preserve the freedom to revise their views.
The tension between speaking publicly and being part of the permanent record is old and persistent.
