This is complete conjecture. Like Truecrypt, Veracrypt is open source, has been audited and has been actively maintained. Could it use another audit? Sure but so could Bitlocker but that isn't happening for even the first time any time soon.
Never heard of any credible reasons to distrust Veracrypt. Don't know who these "people" are either, none of the comments named anything more concrete than what sounds like online rumors.
