It's disgusting for them to say their site should be fine for a healthy individual and that's enough. Not everyone is healthy! And if you're unhealthy and visit a doctor you often won't be instantly cured.

The theme selector is a link in the footer. It's probably the most subtle thing on the entire page. And it's not like they're using the rest of their real estate efficiently. I think it's fair to infer they prefer people don't realize they can change the theme until they've been annoyed.
From the top of the front page, the first section leads to half a screenful informing you to choose a theme. It's the first and most prominent showed to new visitors, promoted on top of the front page.
if I control-f for "theme" the first hit is four screenfulls down (phone) and it's a reference in the middle of a long block of text that implies they have themes.
The first prominent mention of themes is a heading six screenfulls down that mocks you for not changing it. It doesn't tell you how to change it.
This site is an explosion of emphasis. They can use massive size and gradients and flashy colors to emphasize their mockery of me. If they choose not to use the same for their theme switcher link I think it's fair to infer they don't want to emphasize it.
