Walking I call that helping a vulnerable person and don't consider you have broken lockdown at all
re the resignation, his professorship etc - it's only really too good to be true if he's not advising the government anymore. Given his previous projections on foot and mouth, swine flu etc I was surprised he was taken so seriously in the first place.
I am not sure who is to "blame" for lockdown but I certainly think he has a share of that responsibility.
