You seem weirdly worked up over this.

Blinken made no public statements on this until he was asked about it. He did not come out and say for example, "For too long, the vision impaired community have been discriminated against by the systemic bias via the use of Times New Roman. Today we are taking action to change this and restore the dignity of those this font has long oppressed", but Rubio just did exactly this. For all I can tell the actual decision was a recommendation made by an internal team doing an accessibility review.

The only other place I’m familiar with people making grandiose announcements about their font selection, other than a font company announcement, is here on HN.
