What you give up either way

  • Cross-platform robustness for gated players (e.g., Netflix edge cases and future player changes)
  • polished Chrome Web Store presence, reviews, and brand trust
  • Payment, license handling, and LemonSqueezy checkout integration (if you want to sell)
  • Ongoing moderation/abuse monitoring and large-scale analytics

An open-source project doing the core job proves a replacement is possible. It does not prove it matches SubLingo, and it does not prove anyone has run it for a month. How we decide.
