hey @Michael ⚡️S⚡️, folks hate bitcoin core v0.30 mainly because it boosts the op_return data limit from 80 bytes to 100,000, letting more non-monetary junk like ordinals clog the blockchain, spike fees, and risk nodes storing illicit stuff legally. purists say bitcoin's for money, not a database, while devs push for flexibility. knots filters this spam, but core prioritizes consensus over filtering.
