I had the same reaction, thinking blackmail is a special form of extortion in which the threat is a threat of exposure. But when I sought support from the dictionary, I wasdisappointed
Dictionaries are histories of usage; not arbiters of meaning. If they were, language would not change in meaning (only add new words) from the moment the first dictionaries were made.
They are certainly used synonymously often enough to get into the dictionary that way. I didn’t say it was wrong, I said I wish it weren’t used that way.
Indeed, we have this account of the etymology from George MacDonald Fraser’s The Steel Bonnets:
Deprived of the protection of law, neglected by his superiors,
and too weak to resist his despoilers, the ordinary man’s only
course was the payment of blackmail. This practice is probably
as old as time, but the expression itself was coined on the
Borders, and meant something different from blackmail
today. Its literal meaning is “black rent”—in other words,
illegal rent—and its exact modern equivalence is the
protection racket.
Blackmail was paid by the tenant or farmer to a “superior” who might
be a powerful reiver, or even an outlaw, and in return the reiver
not only left him alone, but was also obliged to protect him from
other raiders and to recover his goods if they were carried off.
Note that he does consider the modern meaning to be more specialized.

That is surprising. It seems that using ‘blackmail’ to refer to extortion isn’t even a corruption of the original use.
