I'm glad I'm not the only one that noticed this error. #BlocksizeWar. Good catch nostr:nprofile1qqsd846pynwlkk7uvxu0rrghcve4hw6033c3s234acnnzjjf5n4hk8gprpmhxue69uhhqun9d45h2mfwwpexjmtpdshxuet5qy28wumn8ghj7un9d3shjtnyv9kh2uewd9hsmklmpe for pointing this out in when the episode came out in April! I just finished listening to this episode a few minutes ago and that felt funny to me .
If I remember correctly, the miners "voted" to activate Segwit. *However*, the nodes rigged the vote 😃. The nodes decide the consensus rules and BIP 91 said that a block which doesn't vote for Segwit is - by definition - not a consensus-valid block; those blocks were therefore orphaned by BIP91 nodes. See the 'Specification' section here: https://github.com/bitcoin/bips/blob/master/bip-0091.mediawiki
The nodes are in charge of Bitcoin, and the miners only have power in the very unlikely - and very expensive - case where they can coordinate something like a 51% attack
