The internet has made everything really weird in terms of jurisdictions. You can have photos of UK citizens taken in the UK and stored on a UK server, and if a company from somewhere else scrapes the data without permission and moves it out the UK, that doesn’t obviously mean that it’s now fine to use for whatever.
Now of course the law has to have some jurisdictional limits, but it’s not surprising that there has been some disagreement about where they are.
Ok but LinkedIn and Facebook don’t have a duty to broadcast what you want all over the internet.
They don’t need consent not to share personal information, only to share it.
