What is Syme's observation about Winston's appreciation of Newspeak?

In Part One,
Chapter Five, Syme observes thatdoes not have a "real appreciation" of Newspeak. He
bases this opinion on Winston's writing, like his articles for The Times
newspaper, which demonstrate that he prefers the original form of English, or Oldspeak, as the
Party calls  it:

"In your heart you'd prefer to stick
to Oldspeak, with all its vagueness and its useless shades of meaning."

For Syme, this is a sad state of affairs. He thinks that Winston
does not appreciate the inventive and unconventional nature of Newspeak, a language which is
based on the "destruction of words" and prides itself on "narrowing the range of
thought."

In contrast, the fact that Winston does not appreciate
Newspeak shows that he wishes to return to the old way of living, before the Party took control
and when people had the freedom of self-expression. In other words, by rejecting Newspeak,
Winston rejects the Party's rule.
