This was inevitable, and has been overdue since 2017.
The reason why Labour did so well in that election was the Tories underestimated the social media battleground. This year they dominated it. The only social media site to ban targeted political ads was Twitter. Otherwise, I couldn't scroll through my Facebook timeline without seeing several Conservative ads. If you were to Google "Labour Manifesto" the first result would be a Tory-paid ad for their "Cost of Corbyn" website. Go on YouTube and you may even get a Conservative ad there. Where small, independent, left-leaning blogs were found all over Facebook in 2017, now they are intentionally suppressed, and directly sharing them is the only way to have them seen.
The real winners here are Murdoch and the tech giants. With them at the Conservatives' side, this election and every future one is effectively rigged in their favour. I will vote in every election while I remain in the country, but there is no real value to it, and with the Tories having a huge majority in parliament, there is no chance of reforming our voting system to something other than FPTP which now solely favours the Tories. It doesn't matter if the next Labour leader is on the hard left like Corbyn or a Blairite. Just as Brown, Miliband, and Corbyn was smeared and eviscerated by the media despite being fairly radically different from each other, the next leader will also be up against the media.
Ask a working class voter why they didn't vote Labour, and the answer will be along the lines of what they read about him in the Daily Mail, or that he wouldn't say where the money for his policies came from, despite Boris making similar spending pledges. The weird and kind of horrific thing is, a lot of these people KNEW Boris and the Tories were lying to them, and yet they voted them anyway. Something very weird has gone on this election.
In short, the UK is fucked.
