Sentence with the clerk who can do it, software as uncountable noun

This commit changes two lines.

 (1) Keeping the exact quote with the clerk while having a sentence that
     makes sense in plain English cannot be done, it seems to me, without
     making the sentence a bit longer. Here's one option that seems about
     the best we can do, even though it still sounds a bit funny, because
     it's hard to write a future conditional with the present "can". Since
     it's a quote, it will probably survive the proofreaders.

 (2) Software is an uncountable noun [1], so we say "software is", like
     "water is"; "used software" sounds odd; I added "is itself" to
     emphasise that we're especially talking about the full chain of
     software for running the project. This commit modifies the "When the
     ..." sentence and hopefully sounds better.

 Technically, reproducibility (as defined in \cite{fineberg19}) is possible with non-free or non-open-source software (a black box).
 This criterion is necessary to complement that definition (nature is already a black box).
 If a project is free software (as formally defined), then others can learn from, modify, and build on it.

+When the software used by the project is itself also free:
 (1) The lineage can be traced to the implemented algorithms, possibly enabling optimizations on that level.
 (2) The source can be modified to work on future hardware.
 In contrast, a non-free software package typically cannot be distributed by others, making it reliant on a single server (even without payments).
