Earlier quoted context omitted.
That may be the case, but if the peer made a contractual agreement that limited the peering to symmetrical traffic, then Comcast should be free to renegotiate or straight up sever the peering under the terms of any contractual agreements....if this is what is allowed by what's on the contract. While people can hem and haw about the moral and ethical implications, it seems like this is something that is likely spelled…
There's no technical evidence (you can check, quite easily, who's peering with who and if there's a cost associated) that L3 and Comcast are using a purely-symmetric SFP agreement. It's quite likely they aren't (consumer ISPs would never upload enough to large providers to get a symmetric agreement worth their while.)
