Non-engineers simply cannot understand the technology arguments and so they are manipulatable via social engineering, which in this case is literally legions of paid shills (http://birds.bitcoin.com is the attackers site where shills get paid.)
That's the layer that's under attack now- because the powers that be want to control bitcoin and they can't beat the software, they can't beat the hash power, but they think they can maybe beat the people. (And in Ver's case, he shills BCH to keep its price up while unloading it to get more BTC.)
Actually that twitter account is one that I've seen many times before, and I would not consider him someone who understand how bitcoin works. He seems to be an engineer who has taken a superficial look and then fallen sway to propaganda.
This is the thing about bitcoin, there are layers. Here's some of the layers:
1. "Bitcoin is internet money"
2. A block chain is a chain of database entries
3. I understand what Proof of work is
4. I understand how economic incentives work in bitcoin
5. I understand why PoW will always be better than PoS
6. I understand why ethereum can never work (ultimately)
7. Now I really understand the economic incentives
8. Now I understand bitcoin
Of course this is more than a little tongue in cheek.
The white paper can be found here:
But a lot of the standards are found here (in various levels of adoption)... this bit is really relevant for wallets:
Read the white paper at least once before holding any bitcoin. And then re-read it at least 5 times one the course of 2 years. It has layers and you will come to understand them over time.
Reading Mastering Bitcoin I understand is really useful too. (I got thrown into the deep end of btcd so I didn't have that luxury)
