Criterion's concern is over DVD image quality, and I concur that I would not want to see the blurred frames or the unnatural movement that attempting to preserve the correct pacing would produce. However, I'm also a big fan of silent films, and I cannot stand when silent films are transferred at an improper frame rate, resulting in sometimes ridiculously faster movements, completely undermining the performances of the actors.
Not being technically informed enough to wade into this discussion, I'll give the benefit of the doubt to the decision Criterion is making here, because it is a single frame per second of difference, unlike when a silent film shot at 16 frames per second is outrageously presented at 22 or 24 frames per second.
(Note: In David Bordwell's article, he mentions that this 25-frames-per-second film shooting rate is not uncommon in European productions because of the television transfer considerations. So this is not a unique problem. It just becomes more noticeable with especially long films like Berlin Alexanderplatz (15 1/2 hours), or Sátántangó (1994, Béla Tarr) that Bordwell mentions in his article (7 1/2 hours).)
David Bordwell, along with Kristin Thompson, writes an excellent blog here. Together they are also the co-authors of my indispensable film school book Film History: An Introduction as well as Film Art: An Introduction. A personal favorite blog entry by David Bordwell is "Shot-consciousness", in which he encourages everyone to look at how the shots in a film are framed, and how to appreciate shot composition as an integral part of the art of cinema.
(Since they are usually long, I recommend printing out Bordwell's articles for more leisurely reading and less online distractions.)
