I wonder if this policy that given that it creates free-access to the internet but in the end it also creates a huge monopoly similar to KCOM that kills competition with the added bonus of only the biggest earners footing the bill + taxes dramatically rise due to this. As for the competition, Labour is fine for bankrupting them and what happens if the FAANG companies cannot pay any more or start to relocate due to other economic events such as Brexit, financial crash, etc? How will they continue to fund this initiative?
The astronomical cost of this on the tax-payer and with the current UK economical uncertainty due to Brexit makes this sound hopelessly utopian for a Labour Government to implement I'm afraid.
