Did you try the search I gave you?
I have not heard statements going against this from any lawyers.
I'm interested because my understanding has been most Europeans understood it the same way I did.
Not saying I fully believe that explanation yet, but I'll try to find out more.
BTW and FWIW: I'm not the one downvoting you and I disagree with those who do.
ICO says this [1] about choosing a lawful basis: "You must not adopt a one-size-fits-all approach. No one basis should be seen as always better, safer or more important than the others, and there is no hierarchy in the order of the list in the GDPR."
I think I'll stay clear of your lawyer advise.
