Let me spoon feed it.
BIP110 undermines Bitcoin’s neutrality and risks a contentious chain split, in exchange for only modest relief from “spam.”
More precisely…
It turns Bitcoin from a neutral protocol into a curated ledger. Once consensus rules start classifying some valid transactions as “spam” and banning them, you’ve crossed from “any valid script is allowed” to “only socially approved uses are allowed,” which is fundamentally anti‑Bitcoin, and critically stupid.
It weakens censorship resistance. If node software encodes policy views about which data types are acceptable, this opens the door to future content‑based restrictions driven by politics, regulation, and powerful actors.
It introduces material chain‑split risk for a non‑critical reason. Because BIP‑110 tightens consensus rules that a minority of nodes enforce, blocks that include now‑forbidden data could be accepted by old nodes and rejected by upgraded ones, causing a minority fork over an aesthetic/ideological preference, not a security reason. In fact it creates greater external security risks I’ve already highlighted above.
It sets a precedent that “content moderation at the consensus layer” is acceptable. And thus, it attacks “Bitcoin is hard money” and the “blockchain as immutable.” That’s why it gets a hard ‘fuck off!’
Furthermore, reviewing transaction types in consensus is far more dangerous than the spam itself, because it normalizes rule changes justified by subjective judgments about what counts as legitimate use.
All of these fold into one overarching takeaway: that BIP110 is stupid, and those pushing it are very stupid.
