When I quoted it to you, the quote did say that it was medium to hard encounters, and if you had easier encounters it expected more of them, and if you had harder encounters it expected less.So, now "It unbalances the game in favor of the PCs." becomes "not being challenged at all"?
I know, on the internet, there's a tendency to restate one's position in more and more severe terms if people don't accept your posit, but could we avoid that, please? The resulting hyperbole isn't constructive.
The 6-8 encounters per day guideline is not isolated from other guidelines. Like, six encounters of one normal goblin each isn't going to cut it, right? There is an assumed difficulty of those encounters. So, if you aren't running the same number of encounters, the difficulty of what you do use should change.

The 6-8 encounters represents what the game feels is a challenge for the PCs before they need to rest. You have to adjust the difficulty if you go below 6. If you go too far below 6, then the party can nova pretty hard and trivialize the encounters. Getting a monster that can withstand the player nova means that the DCs and the damage output are so high, that it has a high chance to TPK the party.
