While greatly appreciating your prior efforts in crypto-ccy R&D and
current efforts for Blockstream, its not a plus for your reputation to be
using emotive terms like ³attack², ³fork war" and throwing so much FUD
into the developer email channel directly after Eric¹s email.

We would appreciate seeing your well-argued thoughts, not FUD and flaming.
There are multitudes of trolls in all forums already.
