At least in the real world, free software doesn't demand that you agree with authors or do anything really. For as long as Ole keeps Parallel as free software, we can use it regardless of complying with requests.

Quite honestly, I think the behavior is on the highest order of jerkishness. A nice request could be done in the documentation, instead the path chosen is to bully users of the software.

Once more, because it is free software, we are free to use it despite what Ole thinks. We are free to patch it out too.
