There are no winners in this.
Parents are worried about their children, they want them to have enough education, they are working themselves and don't have the time or the talent to teach, especially if they are working/have younger DC.
Teachers are mostly in the exact same boat as above. They are experienced in doing live lessons where there is to and fro, questions and answers which are also learning points for other DC, they want to praise and coax and inspire. That doesn't really equate directly to a recorded or live non interactive lesson. maybe half of every hour is about supervising work being done, dealing with queries etc and that doesn't translate to provide an hour of content. And lets remember most folk aren't technical wizards either.
I have every sympathy for everyone trying to work in an unfamiliar way with technical issues added in, in short timescales, under pressure and with their own caring responsibilities and home circumstances thrown in.
As has been said, this isn't about individual teachers or even schools, it's about not having a standard model across the country that can be deemed best practice and can be picked up and run with so that all DC get at least the basics evenly.
