These features are available globally on desktop, web, and iOS platforms, with Android support for Photoshop and Acrobat coming shortly, representing a significant strategic move by Adobe to introduce millions of users to its professional applications.
McDonald's Withdraws AI-Generated Christmas Advertisement Following Backlash
McDonald's Netherlands withdrew its AI-generated Christmas advertisement on December 9, 2025, following significant public backlash on social media. The 45-second commercial, created with generative AI elements by Dutch firm TBWA\Neboko in collaboration with American production company The Sweetshop, depicted chaotic holiday scenes and featured the tagline "the most terrible time of the year," suggesting customers escape holiday stress by hiding at McDonald's until January.
The ad sparked fierce criticism online, with viewers calling it "creepy," "depressing," and "soulless," with one user commenting that it "single-handedly ruined my Christmas spirit." In response, McDonald's Netherlands acknowledged the backlash, stating that the experience was "an important learning" as the company explores practical AI usage. The controversy highlights broader concerns about the quality and authenticity of AI-generated content in holiday marketing, as well as the tension between AI cost efficiency and consumer sentiment.
Microsoft Patch Tuesday: 56 Security Vulnerabilities Patched in December 2025
