Have you considered that you are overly sensitive to this, and that you might have been conditioned to be by the manufactured controversy currently being stoked by the right? There are exactly two uses of the word "they" as a pronoun, both in regard to Alon Levy, who presumably prefers this pronoun. It's a big world out there - learn to live with it.
Fantastic response -- D.C.'s flagged initial comment reads as someone who tries to use a blinkered interpretation of language to avoid respecting non-binary peoples' pronouns, while failing to acknowledge the historical use of singular 'they.'
The article features frequent usage of Alon's name, to avoid using they/then as much, just as you would with he/she.
The briefest of searches for Alon's name shows their Twitter profile[1] with "(they/them)" as part of their account name -- which also includes their Mastodon profile[2], itself showing a pronoun box listing "They/them."
It's a shame someone so educated appears to be getting riled up over something so small and trivial -- respecting Alon's pronouns neither harms anyone, nor makes the article any more difficult to read.
"Nonbinary" [sic] people should not be doing "cultural appropriation" of the plural pronouns the rest of us know; if they insist on not being referred to as "he" or "she," then they should come up with their own.
That's literally not what cultural appropriation is.
The fact that you try and use that term when you clearly don't even know the definition, shows you to be nothing more than ignorant and bigoted. Good job.
I'm an intellectual-property lawyer; I'm well aware of what "cultural appropriation" supposedly is — and what it isn't.
(That's why I put the term in quotes. In part, it's to tweak the noses of people who rail against something that the law doesn't recognize as "a thing." What those folks call "cultural appropriation," the law calls "laudably propagating good ideas and practices, subject to any applicable restrictions that have been duly enacted into law.")
Apparently not, since you think that "plural pronouns" are a cultural element that can be appropriated, which isn't the case when aforementioned pronoun has centuries-old singular usage -- notwithstanding the significantly greater usage and acceptance in modern times -- with the extreme minority being the bigots who attempt to deny both grammatical and historical fact, and language evolution -- because of their own bigoted, hateful views.
Being an IP lawyer won't win you any points, especially when you're ignorantly refusing basic facts of language even with empirical evidence.
