why people still pay for Transistor
People still pay for Transistor because creators pay to remove fragile audio plumbing and publishing chores from a release schedule. The recurring cost buys codec support, loudness standards, transcription, storage, feeds, analytics, and deliverability to directories, not just the visible interface. If none of that applies to you, any pick above saves $228 a year.
