Airbnb has the information that is shown in those examples because that user has given them the info (by registering). If someone is using a website it's reasonable to expect that analytics is tracking every move in order to make proper business decisions. If that user has registered for the application, it makes even more sense to attach their actions to their account so you can track customer lifecycle data in order to improve your funnel and decrease churn.

If you don't want a site to gather info about you, then don't use the site. Or use incognito mode I suppose.
