I think these 12 hours is a real problem for following reasons:
1) The fix concerned security and as such it had to be adopted immediately. Someone citing "emergency" character should understand this is rather aggravating circumstance, not an excuse.
2) They must have had the sources before released binaries. What was the reason/purpose for not disclosing them for 12 hours? It had to be done intentionally. Are there better and worse players, some who award the security and the rest that do not?
3) Do you think an exchange or any other serious company can work straight with binaries, especially unsigned? Aren't their operators supposed to audit the sources?
4) How much can a crypto change it's value within 12 hours? Can you imagine such a rapid change while all your assets are frozen and you can't do nothing because all major exchanges disabled your wallets? Isn't it like someone deleted your Bitcoin by erasing it's value while locking it "temporary"?

I have not yet got involved in BTC vs. BTU discussion till now and my opinion is not partial for that.
Did BTU team give any explanation for that what has happened? Did they encounter HDD failure?
Do they find such a practice normal and are going to exercise it in the future?

The users only control killing Bitcoin by selling it. Otherwise they control nothing in face of a 51% attack.

Please stay on the facts.

Sorry but I reject your idea that there is such thing as a mining cartel.

Miners control the hashing.  Users control the economics. 
 

BU activation at 51% could happen because of some rogue miner who produces a block of over 1 MB, I don't think that is BU's strategy.

-> Satoshi will never come online because that may lead to chaos on bitcoin market.

In my opinion I think the worst thing that could be happen is that BU is only a possible prelude of a "private network" and a prelude of a way for patents registered.

BUcoin is dead. Nobody will use inferior software commanded by a mining cartel when you got world class coders working in Core with a new non-centralized mining algo.

Miners can be easily replaced, coders can't. Can't wait to dump BUcoin.

Its my personal belief that the BU faction is enabled and encouraged by the Chines mining pools who are in turn controlled by Chines government oligarchs.  

After a theoretical continuous hard fork between Bitcoin Core and BTU the mining pools who initiated the fork would be in full control of the BTU chain. They would have 95% of the hash power. Its my belief that if they fail to win a majority of the Bitcoin communities support and the price of BTU coins starts to fall dramatically below the price of Bitcoin they will halt all transactions on the BTU chain other then their own coins so they can flash sell for a huge profit before pointing their miners back to the Bitcoin Core chain. They will have lost there bid for complete control over Bitcoin but they will have made millions. It is known that Chines miing pools are sitting on millions hundreds of thousands of bitcoins.

This shows us that there is absolutely no need for Bitcoin Unlimited or I do not know what other scaling solution that is absolutely not needed.

Let's put that to a test right now. I am going to refute you and let's see if the market is paying attention, because miners damn well better be paying attention.

Perhaps you haven't noticed that before I made my shocking math post, the Bitcoin price was declining, since I made my post then the BTC price has risen 5% and miner support for BU has declined. I think the market is paying attention and that is why I am following up with more explanation (when I should be sleeping instead because it is 2:30am where I am and I am on medications).
