The expression which debunks saying that
something is "fortunate" or "
unfortunate", because they do not specify who
benefits or looses as a consequence of an event or outcome.
"Fortunate" and "unfortunate" are now debunked and archaic words. They are being replaced by "good for but
bad for".
Because saying that a thing is " fortunate " or " unfortunate " does not specify who benefits and who looses. Thus, it's best to, for example,
say, " It's good for A but
bad for B that ____________________ ( a specific thing happenend ) " .
