Maybe because of this:
"Feb 4 (Reuters) - Snap Inc (SNAP), owner of popular photo-messaging app Snapchat, on Thursday warned that upcoming privacy changes by Apple Inc(AAPL) could hurt Snap's ad business although fourth-quarter results beat analysts' estimates for user growth and revenue.
Snap stock declined 7% to $54.02 in trading after the bell.
Snap said Apple's(AAPL) planned privacy changes, which will ask iPhone users to consent to personalized ads, could present a "risk" to advertiser demand, but added it was unclear how the changes could affect Snap's business in the long-run.
"The disruption to ad targeting caused by the iOS 14 privacy changes will clearly be a worry for Snap, which has been steadily growing its armory of ad formats and advertisers," said Tom Johnson at ad agency Mindshare Worldwide.
Facebook Inc has been waging a public fight against Apple's(AAPL) changes, accusing the iPhone maker of anticompetitive behavior and hurting the social media company's ad-targeting business."
