No company cares about you, but Facebook probably cares more than other big tech companies (Google, Microsoft, etc.) if only because your feelings drive your usage of its services.
Actually, you can reach actual human representatives at Microsoft. You absolutely cannot at Facebook. I don't wanna bore anyone with my most recent story but you really can't. And I was an advertising customer too, not just a regular member. They care so little that when I challenged my Paypal payment to them, trying to force a human response out of them, they let it default and I got my money back from Paypal. You gotta admit that is pretty remarkable.
That’s a poor generalization. A company, as a legal entity, is incapable of caring. But a company, as an organization comprised of people, can.
At Facebook’s scale, it would be very difficult for their employees to care particularly for any individual user, but collectively, it’s not out of the question.
Customer service is the way to people's hearts. Ultimately, Facebook and some of these other companies are using bad business practices and it has to come back and hurt them eventually.
