That article is needlessly dismissive of the 88 dog whistle, refusing to explore the idea of "plausible deniability" at all, and it completely ignores the other right-wing dog whistles he engaged with on Reddit threads, like "triggered" (which he claimed he didn't know was right-wing, but at best his use of it shows that he is hanging out in right-wing spaces enough to have learnt through osmosis what the correct right-winger's way to use that term is). I'll repeat a comment I left in a Lemmy thread back when this was fresh:

I thought this comment (and the thread below it...and the lack of any reply to it despite the CEO being all over the thread elsewhere) was pretty telling.

It's much less of a strong tell, but is slightly concerning that he's picked up language like "triggered". As comments there say, his excuse of not being in-tune with American politics could be real, but are also possibly just plausible deniability, because he may have picked up on that language by hanging out online with fascists.
