Holding people to obligations they themselves have taken on seems like a reasonable thing to do, but what do I know.
TFA even illustrates why it is necessary. Pereira got her landline cut without a suitable replacement in place:
>Pereira has relied on her landline for 58 years. She got a cell phone for the first time last year when her landline got disconnected, but she lives in a dead zone for cell phones. CBS13 had a hard time getting in touch with her because the call kept dropping.
Stop defending telcos weaseling out of their obligations when they have taken public funding for decades in order to provide a utility.
