The fact at issue, at least as I understood it, was not whether people were _forced to shift their service_ from copper to fiber or cable, whether or not they wanted to.
The asserted fact was instead that, after people had voluntarily shifted their service away from copper to fiber or cable, the (now unused) physical copper infrastructure was removed or cut or in some way permanently disabled such that there could never be any return to it, and that this was done in many cases without their knowing or being told that this would happen.
Don't know for certain whether this latter version has actually happened or not -- but I've seen it asserted numerous times.
