I wrote Open source ≠ immune. This does not imply that Closed source = immune or Closed source better than Open source.
What type of bad development practices I refer to?
I'll mention just a few because they are too many.
- SegWit (BIP141) - Non-monetary payloads (inscriptions/ordinals, large scripts, vanity) became structurally cheaper than monetary bytes.
- Taproot (BIP340–342) enabling cheap complex scripts & data tricks - Arbitrary data embedding (e.g. inscriptions) became easier to route through witness without tripping legacy filters.
- Datacarrier "policy" liberalization (OP_RETURN & standardness) - Higher legal and operational risk for full nodes (content relay/storage), more mempool congestion; sovereign hobbyist nodes face higher cost/ liability calculus.
