(Mike Mozart) Data caps on home broadband stink, but they’re also a reality for millions of internet users (and probably soon for all of us). And as the FCC’s new open internet rules go into effect in the coming days to protect net neutrality, they’re also becoming one of the main ways in which ISPs can soak up extra cash from consumers and businesses alike. Ars Technica noticed the filings with the FCC this week, in which AT&T claims that their data caps are high enough for most users and most use, and so therefore these deals won’t actually harm anyone — and in fact, are actually better for consumers and competition. AT&T places data caps on not only their mobile data services but also on their traditional fixed wireline broadband services.
