For me personally, the accessibility issues would be with elements used out of their usual role.
For example: When I, blessed with being sighted at this time, but without a mouse, ask my browser to identify the clickable/actionable elements on the page, it mis-identifies both unclickable elements as clickable, and clickable elements as unclickable.
I would call that a serious usability issue. And if I was not sighted, using a screen-reader, I would be very confused indeed by this landing page.
I agree that whether this qualifies as a "huge" usability issue is indeed a matter of opinion. I would certainly argue that it is a huge usability issue.
`section` has an `h2`, but no `h1` for some reason. Other failures like this.
Other than that what's wrong?
User agents rely on ``a`` elements being clickable, and ``span`` elements not being clickable, for example, to determine which actions to present to the user.
When you use them outside of these use cases, the user agent has to do extra work to figure out whether something is actionable or not, and not all can do it adequately.
