It's all just an underhanded way to force businesses to pay for adwords. While these added "services" such as places, youtube, news, etc.. are not part of the algo update, they are certainly intentional and have been part of the business plan for years. They've been doing it slowly so people get used to it.
They also disguise those top 3 adwords spots to the point that most people don't understand they are even ads. I've had to explain that these 3 are actually ads to many people in the last year. For all the 'webmaster guidelines' and other propaganda, they are sure leading the way in spammy underhanded site design.
As far as the algo and panda update, this is also in my opinion, absolutely designed with the sole purpose of forcing people to use adwords.
We see obvious signs in the title changing, and other strange ranking behavior. The goal is clearly to make it hard for people to choose which keywords they rank for unless they pay insane cpc prices directly to the big evil. It's as if they're saying:
"If you pay, you can choose your keywords, if you don't pay, we're going to rewrite your titles, choose strange text to display in the serps and rank you for unrelated phrases."
