I've seen complaints about the addition of Santa Hats, and splash screens, but it takes three elements to potentially infringe this patent:
1. Change the company logo itself. Not an icon, not a photo, the company logo.
2. The change has to be animated.
3. The logo has to be a link to a website or search results regarding the holiday, so if it is selected the results are shown.
Find me a prior art piece like that, and you can go back to complaining.
