If you want to understand better the ABC upgrade and why it's the only reasonable proposal currently:
It shows even more the contrast between ABC and SV. ABC has boring tech and math talks while SV has mostly propaganda behind it. Doesn't it sound familiar to you?..
The comparison between Core and SV are more apparent than ever before: SV like Core has little to offer on technological grounds, they are mostly busy spewing slogans and ad hominem.
ABC here talk 100% about their work and not about "Satoshi's Vision" (sounds fmailiar?.. "We are all Satoshi!" was part of Core's Proof of Propaganda).
Don't forget that they also block anybody on social media that do not agree with their "Satoshis Vision". Creating another walled garden much? Doesn't it sound familiar to you?
