Well, in that particular case, the price would be similar to the costs
of other instances of inaccessibility:

1. Loss of audience, with the attendant loss of funds or influence.

2. Denial of the audience's rights, with the attendant ethical, social,
and legal risks.

I think the question of denying the entire audience content which is
only accessible to part of the audience and the general question of how
to promote web accessibility via a specification are large and
interesting ones, but there is a serious risk of them sidetracking
discussions of the technicalities of making content accessible in the
first place. These questions are not "canvas" specific - the same
discussion has been had around "alt". So I'd recommend separating the
three issues:

1. How do you make content (e.g. "canvas") accessible to end-users?

2. How should HTML5 encourage use of its accessibility features?

3. How should HTML5 consumers handle partial content? (e.g. "img" with
"alt" but no "src")

Without decisions about (1), questions (2) and (3) are pretty valueless.
