I haven't seen that. It's a very long thread! I don't even know how this discussion first started
I was mainly trying to add a bit of historical context, in a broad brush stroke kind of way. As regards proper social rented homes, the basic facts are that 2 million have been sold under RTB and that has also reduced the stock of social rented homes by 2 million. This is because in 1980 very tight restrictions were brought in on councils building social housing for rent. Housing associations built a smaller number, but these pretty much just replaced the social housing that was torn down over the past forty years. So, we now have a situation where we have 2 million fewer social rented homes than in 1980.
In 2020, the rules on councils building housing were relaxed, but there are still barriers. Not least practically, after being out of the business for forty years! From Googling I think you are talking about the Affordable Homes plan for the next few years. Under the last plan, only a small percentage of these homes were for social rent. I don't know what the plan is for this new one.
