I‘ve discussed in the past how many people mistake privacy as some sort of absolute „thing“ rather than a spectrum of trade-offs. Leaving your home to go to the store involves giving up a small amount of privacy, but it‘s a trade-off most people feel is worth it (not so much for some uber-celebrities, and then they choose other options). Sharing information with a website is often seen as a reasonable trade-off for the services/information that website provides. The real problem is often just that the true trade-offs aren‘t clear. What you‘re giving up and what you‘re getting back aren‘t always done transparently, and that‘s where people feel their privacy is being violated.
