From an accessibility perspective, I wouldn’t be so dismissive.

• A contrast accessibility calculator shows that concerns about color contrast go beyond personal taste. (edit: looks like this will be addressed, acc. to a follow-up post).
• Elements like links violate WCAG 2.2 SC 1.4.1: Use of color by using color alone to distinguish meaning, which is especially problematic here since the first links are also headings; making them bold and colored seems to rightly suggest a heading but not a link. A visual distinction that specifically suggests a link, such as an underline, would fix this.

Beyond what people were saying in those threads: the list entries with list-style-type: none won’t be read/navigated as bullet points by a screen reader, but most screen readers will announce every single black heart emoji.
