Until yesterday I was not totally against Bitcoin Unlimited - at a first glance it seems to be an attractive way to adapt block size to the needs of users and miners. But this event shows us that it's basically beta (or even alpha) software. And I really fear worse things could happen to BTC if BU really becomes the dominant chain, as after looking into the details even from my layman's view the consensus method could lead to different types of "attacks" from interest groups to rise or shrink the maximal block size.

Changes of this magnitude should really be tested and reviewed extensively.

For now, because of this event, I am again more in favour of the Core fraction, although I would prefer a conservative maximal block size increase of 10 or 20% per year.
