my concerns come down to "i'm worried what the telecoms might do because i don't trust the telecoms"
it's less about what specifically they can or will do, but the longer-term problem that they do not have my interests at heart, and are on a continuous path to degraded service, higher prices, and worse access. this is just another step in the pubnet's commercialization.
we have every reason not to trust major telecoms. we have every reason to replace them with local ISPs.
