You raise an important point, which is that the game itself is constantly changing, and not always for the better. If you loved the game when it launched, too bad; that game doesn't exist anymore and you can never play it again. This is one reason why you'll see 500 hours of playtime attached to a negative review - it's not necessarily that they played it so much they got bored with it; it might be because the aspects of the game they enjoyed have been removed or ruined.
Amen to this! I was very much enjoying 2.3, and then 2.4 came along with a basket full of game-breaking and generally annoying bugs (PS4). Had I reviewed 2.3 on Amazon, I would have given the game 4 out of 5 stars, perhaps even 5 out of 5 with an explanation that it's not perfect. If I were to review it today, I'd give it 2 out of 5 stars along with a scalding review and half-a-dozen screenshots showing how broken it currently is.
I'm just keeping my fingers cross that the game I love will eventually come back through bug fixes, someday...
