You can try to avoid the discourse, but if you're American then you're in it. This administration is destroying the country for many reasons: profit, hatred of democracy, racism, control. And FWIW, it's the current administration foaming at the mouth about a font change, not the last one.
In this case, the decision is solely because the last guy did something and they can't let anything from the last administration stand.
Let's say, in an alternate universe where Rubio's department genuinely thought there were cost or coordination issues with Calibri. They could have reversed the decision and cited that. But no: Making a font that is more compatible with screen reader technology is woke. Their words, not mine.
