Is there no comparable alternative tool in active developement than MCSE (MediaCodecSpeedEdit)?
If he does not keep to develope it, it is considerably absndonware. No reason to keep the source code closed.
If Ala42 made money from it (like Peter IsoBuster) during active developement, keeping it closed source would be reasonable. But otherways, it cripples developement unless there is a compareable open-source, cross-platform alternative software.
