https://bitcointalk.org/index.php?topic=1376633.0Announcement: We will withdraw support from February 21s roundtable consensus, unless Adam Back gives us a reasonable explanation why he quietly changed his title from Blockstream President to Individual at the very last moment without anybody noticed. We feel weve been cheated. I dont know how we can trust Blockstream anymore in the future.
I don't quite get his problem. It's pretty clear that A. Back change it to avoid controversy, but they all new very well (or should have) who is Adam Back and who he represents. So what difference does it make for f2pool?
