Well, we haven't had a 2nd referendum on Brexit, so there should be hope from that. A lot of Labour voters these days seem to not understand the unaffordable consequences that you mention...
Its not necessarily unaffordable if you're using joined-up thinking rather than just doing something and ignoring how it impacts everything else.
Are Labour using joined-up thinking here? I'm honestly not sure.
On the one hand I think nationalising infrastructure is GOOD. Splitting off telecoms, water, gas, electricity, has made a complete mess of those things.
On the other hand, I don't think having just one national ISP is a great idea due to the many issues we have discussed - not least our privacy and content filtering potential. I also think its bad timing, with Openreach FINALLY deciding to push forward with Fibre First. I think it will impact me personally in that my exchange being due to start being worked on any time now, will probably now get delayed until after the election. If Labour do get in I'd imagine it would be delayed even more, due to the uncertainty of how things are going to proceed.
There are just far too many pressing issues the government would need to deal with BEFORE taking over Openreach, and the potential legal challenges they will get from that. Its likely to delay FTTP roll out longer than just leaving Openreach to their own devices at this point.
