History Lesson: When Blockstream visited pool operators ...

Hey there,

I need some history lesson on this. I remember that around the time before the fork there were visit(s?) of Blockstream employees to one or two mining pool operators. Before the visit the operator was against Segwit and promised to not have his opinion changed, after the visit he/she flipped. I can't seem to find any information anymore on the visit. Am I crazy or did this happen? I think it was around the time of the Hong Kong Agreement.

Who flew to which operator? Back then I just couldn't understand how they managed to convince him. Re-watching BarelySociable's video I wonder if they maybe privately revealed Back's signature from early blocks.

Cheers
