sadly FT it seems have got a bit more aggressive, they used to allow a few views per month free to everyone, then free registered users would get about 10 views, seems now both those options have gone.
Ok a fix for ublock origin users.
Disable first party scripts on ft.com
Allow inline scripts in no-op mode on ft.com
Then the free registration access works again, if you have no account it will offer to allow you to make one for free.
To do the above you need to be running ublock origin in advanced mode, also make sure you allow cookies.
