Disagreed :) How @alt is presented is up to the UA. A tooltip is nothing more
than one possible implementation[*]. If that implementation satisfies the
need for @alt as defined in the spec, that's fine. When it doesn't, the
implementation is broken. @alt marks not a tooltip, it marks a textual
equivalent. That's all.

[*] Lynx and iCab for Mac OS 9 for instance provide access to @alt, but not
through tooltips.

Providing easy access to the equivalent is beneficial. Whether that is done
through mechanism x or y is irrelevant, as long as it gets the job done.

Well, I wouldn't dismiss the usability/accessibility problems he notes. But
yes, the article is about broken implementations (in UAs), not about the alt
attribute (in the HTML spec).
