Verizon still employs its own unionized workforce of service technicians for cable connections; Comcast outsources that to multiple competing front-line service contractors.
This isn't a system that can't ever work, but Comcast has not yet solved the problem of keeping communications channels clear and coordinated among different competing contractors who have no incentive to cross-communicate with each other (not only are they not rewarded for it, but the incentive system of free markets is actively structured so that if one contractor looks bad, others indirectly benefit). It leads to all sorts of little micro-aggressions; when I had Comcast hooked up at a previous residence, the contractor had to climb the ladder to the pole twice because the junction plugs that should easily wire my house to the main trunk were not only detached, but removed (likely by a previous contractor, because hey, free plugs). He had to go down and get new plugs and splice them in.
In contrast, everyone is on the "same team" at Verizon, structurally and legally. You leave the junction plugs there because the next guy who comes along and needs to connect the service again is your coworker.
It's a shame that none of that matters to this individual because of the way the service local monopolies are structured in the U.S. Living near a major metropolitan area, I'm lucky enough to have my choice of the two vendors around here.
