Maybe because true is just one special value (which also evaluates to "true").

If you want to test that x is true and nothing else than it is
excellent practice to write

if x == true then

this however is so rare a semantics that Robert and Paul are
completely correct with their statement, because in 99% of the cases
what you mean is

unless x.nil? || x == false then

which of course can and shall be written as

if x then
