I empathize with many of the complaints, but some are a bit ridiculous. Using custom fonts in software UI is completely reasonable and normal, even if you don't like it.
Reasonable? That's subjective. I don't think it is, personally. Normal? Unfortunately, yes.
I remember a time when UIs looked consistent, instead of custom-branded, and I still think the "completely reasonable and normal" state is the former, not the latter.
