What are you talking about, basically every tier 1 carrier is going to charge you based on usage. Usually per average mbps or gbps with a minimum commit (so you'd buy, say, a 100G link with a 10G commit, then you pay $x per gbps using 95th percentile[1] with a minimum of 10gbps). The only exception is if you peer and have a bilateral agreement, in which case you pay nothing anyway. If the ISP you worked at used other ISPs (tier 2 or 3) as upstreams then yeah, you get the same service as business class internet (flat rate for a capped link speed) but once you're one of the big boys it's absolutely metered and charged by usage.
