Author of the linked article made a mistake. BTG fork is indeed scheduled in Nov, but the distribution will be done as per 'snapshot' block, which was mined yesterday.
So, if anything, the dip in price could indicate that a lot of bitcoins have been purchased for the sole purpose of claiming free BTG, and those bitcoins have been dumped (either for fiat or alts) right after the snapshot block.

Then the decline in support for BTC is a direct consequence to what the market (i.e investors and traders) view, at best as a non-event, at worst, a failure.
EDIT: in both cases, this does not look good, and I don't have to press hard for evidences, it's all over the news:

McKay is in this same boat, backing the underpinning technology.
"Most people in the world aren't talking about Bitcoin. They're talking about Blockchain, the distributed ledger private or public that underpins the Bitcoin application of it," said McKay."

This does not work. Any currency needs stability and transparency, otherwise you will get all the illegal activities in the world. Why was the ransom for the virus (wannacry ransomware) collected in bitcoin? Why has China cracked down on bitcoin?"

Last but not least: “Fees are not strictly enforced like transaction fees in normal banking, but if you don’t include appropriate fees, there is a serious risk that a transaction won’t be processed by a miner.”
