  To be honest, this page dates back to half a dozen years ago and
reflects Gáspár Sinai's positions at that time; there are hints that he
has changed his mind at least slightly, as he started to make quite a
scandal about possible "security problems" in the bidi algorithm and
later backed off (http://yudit.org/security/).  This is of course not to
say that the bidi algorithm is perfect, because it's not, but I don't
think that the link you quote makes a really strong point against it.
In particular, I find that some of the recommandations Sinai criticizes
are amazingly close to what we do in the TeX world ("formatting codes
should be inserted" => mark up the text with direction-switching
commands, etc.)
