There are ways around this with some models, but it's been a long time since it was even "save SHSH blobs and replay them" easy.
For this type of legislation push it is very important to keep the narrative focused on what’s morally and technologically reasonable.
Very few people agree that a manufacturer should be forced to spend time and money on supportting a product for life, many (I hope) agree that we should force manufacturers to give us the ability to repair all functions ourselves (or at least not stand in our way), but almost everyone can agree that you should be able to replace something as trivial as a button, a cable, or a screen.
Absolutely, the more the merrier. Also, I believe that lay people are now becoming aware of the fact, as I've seen many articles both in the daily press and on the television news about it (where I live the Government's current inquiry into the matter seeking public comment has been reasonably well covered).
Glad to see the BBC running this.
