I would guess this article is an effort to distance themselves from this dev if people google it

The developer of 86Box as a rule has a history of backing up their claims -hence 86Box which has gone from strength to strength in the years since being forced to fork from pcem.
A *LOT* of people float into the project's discord and ask "pentium III when?" -this addresses that, as well as answering the overly ambitious promises made by a recent fork of 86box.
Having the wrong scope can be very detrimental to a project in general, and although I'm not an emulator developer I feel this is probably especially true in this case.
