The first person pronoun you used ("I") strongly implied personal use.

No, it just means the person has the ability to purchase. They could be purchasing it for themselves or on the behalf of another organization.

I accept that, in a literal sense.

I was attempting only to answer the question and explain the source of confusion.

In native English speech, it would usually be expected that a business-case purchasor would speak of a more general case, perhaps by using "we".

Ah - I took the question as saying “I did nothing to indicate the sort and could in fact be purchasing for a business”, so I was trying to explain that side!

In English, when purchasing on behalf of a corporation, “we” would almost always be used.

“we” is even frequently employed by auctors writing papers to depersonalize.

I guess it’s just me then. I wouldn’t write “we” in a comment online without explaining who “we” is, it seems like an unnecessary detail to explain

That’s how I meant it. Seems odd to say “we” out of context like that. And anyway I would be the person purchasing so including the whole company is.. odd.

Anyway, I guess this is the pedantry we (!) should expect from HN
