Maybe you're right, I can't say that resonates with me but I may well be in the minority. I do find it interesting though that the post you link to has this as it's first sentence:
"After six and a half years, Guido van Rossum, the creator of Python, is leaving Dropbox and heading into retirement."
No ambiguities regarding the reasons for the post then.
(Also, for what it's worth, I had no idea who Arash was prior to reading this post.)
"Arash – our co-founder and great friend – is leaving Dropbox for new adventures."
Just one simple sentence like that at the top lets us know the rest of the post isn't a eulogy, or at least not the kind where someone passed away.
Any other point in time when there isn't a global pandemic you can leave that out, but right now times are weird and confusing.
