It's becoming clear to me that a lot of people don't understand how fragile bitcoin is. Eloquent explaination of why decentralization is important. https://www.reddit.com/r/Bitcoin/comments/59kflj/its_becoming_clear_to_me_that_a_lot_of_people/

There is academic research showing that even small (2MB) increases to the blocksize results in drastic node dropoff counts due to the non-linear increase of RAM needed. http://bravenewcoin.com/assets/Whitepapers/block-size-1.1.1.pdf

Reddit summary of above link. In this table, you can see it estimates a 40% drop immediately in node count with a 2MB upgrade and a 50% over 6 months. At 4mb, it becomes 75% immediately and 80% over 6 months. At 8, it becomes 90% and 95%. https://www.reddit.com/r/Bitcoin/comments/5qw2wr/a_future_led_by_bitcoin_unlimited_is_a/dd442pw/

segwit is not too complex https://www.reddit.com/r/btc/comments/57vjin/segwit_is_not_great/d8vos33/

segwit does not make it possible for miners to steal coins, contrary to what some people say https://www.reddit.com/r/btc/comments/5e6bt0/concerns_with_segwit_and_anyone_can_spend/daa5jat/?context=1

https://keepingstock.net/segwit-eli5-misinformation-faq-19908ceacf23#.r8hlzaquz

segwit is required for a useful lightning network It's now known that without a malleability fix useful indefinite channels are not really possible.

segwit is bigger blocks https://www.reddit.com/r/Bitcoin/comments/5pb8vs/misinformation_is_working_54_incorrectly_believe/dcpz3en/

typical usage results in segwit allowing capacity equivalent to 2mb blocks https://www.reddit.com/r/Bitcoin/comments/69i2md/observe_for_yourself_segwit_allows_2_mb_blocks_in/

Why is segwit being blocked

jihan wu (head of largest bitcoin mining group) is blocking segwit because of perceived loss of income https://www.reddit.com/r/Bitcoin/comments/60mb9e/complete_high_quality_translation_of_jihans/

witness discount creates aligned incentives https://segwit.org/why-a-discount-factor-of-4-why-not-2-or-8-bbcebe91721e#.h36odthq0https://medium.com/@SegWit.co/what-is-behind-the-segwit-discount-988f29dc1edf#.sr91dg406

or because he wants his mining enterprise to have control over bitcoin https://www.reddit.com/r/Bitcoin/comments/6jdyk8/direct_report_of_jihan_wus_real_reason_for/

Segwit is being blocked because it breaks ASICBOOST, a patented optimization used by bitmain ASIC manufacturer

bitmain admits their chips have asicboost but they say they never used it on the network (haha a likely story) https://blog.bitmain.com/en/regarding-recent-allegations-smear-campaigns/

the UASF caused segwit activation

"The supreme art of war is to subdue the enemy without fighting." ~ Sun Tzu. The Art Of War.

The UASF had one goal and one goal only, activate segwit via BIP141 on 1st August 2017. It succeeded.

uasf delivered the goods for bitcoin, it forced antpool and others to signal (May 2016) https://bitcoinmagazine.com/articles/antpool-will-not-run-segwit-without-block-size-increase-hard-fork-1464028753/ "When asked specifically whether Antpool would run SegWit code without a hard fork increase in the block size also included in a release of Bitcoin Core, Wu responded: “No. It is acceptable that the hard fork code is not activated, but it needs to be included in a ‘release’ of Bitcoin Core. I have made it clear about the definition of ‘release,’ which is not ‘public.’”"

The core developers did not have consensus in favour of the UASF, yet it still happened
