A Goldman Sachs contractor apparently mis-addressed an email to @gmail.com instead of @gs.com and because of this Goldman Sachs requested that the email is removed from the recipient's inbox. Google initially refused to comply with the request but nonetheless blocked the respective account in the meantime.

I am not sure what worries me more, that the usual "ruthless" global investment firm is actually willing to go to such extents to "protect" data they mis-addressed themselves (what happens with a physical letter? Torning down the house?) or that a similarly global company in the IT sector manages to withstand only for a few hours (best days) and eventually gives in and blocks the account in question (at least they havent "secretly" deleted the message, it appears).
Is the conclusion we need to draw here that literally any Gmail account can be (indefinitely?) blocked if someone with a big enough budget accidentally addresses an email to it?
