> As I said, laws that prohibit companies like Apple from disclosing something are very different from laws that force them to affirmatively make false statements.
1. Apple tells users that they don't snoop on iCloud data, and sprinkles this marketing statement by assuring users that they are literally incapable of doing so.
2. US government lawfully forces Apple to gather and share intelligence, with an adjacent gag order. Apple changes a few settings on their backed and issues updates to to iPhones, along with publicly disclosed changes. Apple - as any business wishing to still exist in a year (or the management wishing to keep their seats) - complies with government's demands to the letter.
3. Gag order literally renders Apple and any person aware, [edit: s/incapable/disallowed/] of stating "we started logging this data" or "we have not been logging this data in the past, but..."
4. Apple logs and shares data, has to lie to customers to abide the law.
