Excellent article !
And finally, what one considers Bitcoin is now open to interpretation and simply because one fork managed to politically keep the ticker BTC does not mean that it is in some way more or less inherently entitled to the name of the main chain.

BCH is Bitcoin
BTC is Bitcoin
If a tree has two branches, you do not consider the two branches to be separate from the tree. At the time of the split, there was no "correct" main chain, just the one which was perceived to be the main chain because they used their political positioning to maintain the original ticker of btc. The valuation of these two forks is in flux, people are still struggling to grasp the technological, political, and economic concepts at play here. There is no clear winner yet, this will take months to settle.

BTC split from "The" Bitcoin chain via segwit.
BCH split from "The" Bitcoin chain via raising the block size.
Both forks implemented changes, thus while one kept the stock ticker of BTC and the infrastructure built around the BTC ticker on trade platforms, it is not inherently the defacto Bitcoin.
If BCH manages to maintain the majority hashing power and prices rise to support it, it will become the chain which is used and referred to as the main Bitcoin.
Obviously, this could not happen within the same day of launch, or week, or maybe even month or months. This will take some time to play out. Right now there is a great deal of uncertainty among investors, traders, and miners.
A great deal hold both of their coins, BTC and BCH and use BTC + BCH to calculate the overall bitcoin price, which is a sensible way of understanding this.

Finally, when somebody says Bitcoin, it is now a general term which could be perceived to mean BCH or BTC.
There is a lot of doublespeak around this situation, many people are vocal about supporting one side while others are silent and willing to follow whichever appears to be 'winning'. This is like poker, people may not want to telegraph their moves because there is no clear advantage in doing so. Only time can tell where this leads.
