Many of the original / more important tapes were digitised to enable easier access for all. Some of these were then destroyed, no point in expensive housing once copied over; but the data remains in digital format instead.

missing telemetry

Some of the telemetry recorded during the Apollo era (and in fact the rest of spaceflight history) have been deleted. Why do we need to hold on to data on heartbeats or blood pressure of an astronaut when there is nothing being learned? Some forms of information just isn't worth keeping. However the pressure / thrust / temperature / vibration from a malfunctioning engine would be useful in future re-designs. So some data has been deleted, some held for all time. Why would such actions be signs of a hoax please?
