Earlier quoted context omitted.
I am not sure if losing Facebook access counts as losing any kind of "technology". They cannot block the use of their FOSS code in Europe, isn't? I am not sure the impact of closing their offices in Europe, though I am sure their the most interesting work is done in USA.
I agree that Facebook isn't really "technology" and that losing it would probably be a net positive. I am worried that Europe will set a precedent that will discourage internet technologies from doing business in Europe disconnecting them from the world.
That would be great for diversity, not to mention provide a fertile playground for much-needed alternatives. Too bad it probably won't happen.
