Eh. While this pack seems largely unimpressive (and with the Sims 4 addressing eco-living related content twice before, obviously recycled, pun not intended), I do welcome the grittier, dirtier, more dreary look that the pack... tries to deliver since it's painfully clear that the Sims 4 is mostly a utopia, goody-goody, feel good, safe haven-esque kind of game. (see "snowpals")
It's difficult to grasp exactly how the OP feels about this pack, (I only say that since while he's using exclamation points and such, I've never seen anyone feel strongly against a pack because of a few minor pieces of content within it) but he seems to be overreacting a bit. It's not as if the Sims 4 (or previous Sims games) hasn't crossed the avenues of potentially gross content before. Forcefully sucking blood from another individual or kidnapping them to impregnate them with an alien seed? Both are disgusting acts to do in real life, yet the game contains these acts. Plus, it's great for hobo characters or an apocolypse-like playthrough for those who wanted to simulate such things more easily.
This is obviously completely subjective, but it seems wiser to me to judge a pack based on its overarching effect on your game and whether or not its content improves your playstyle, not based on extremely minor features of the pack. Meat walls can be easily ignored, even for vegetarian Sims. Dumpster WooHoo is not forced upon the player because there are numerous other locations your Sim can choose instead and eating bugs... it's not as if consuming insects are the only option for Sims to eat. The OP argues that our Sims are not animals. No, I say his Sims are not animals. I might want to play a character that roughs it. Perhaps I'll want to recreate Gollum in the Sims 4 as accurately as possible, for example.
Videogames often require a certain level of disconnect and disbelief to find them enjoyable. I'm not sure the OP has enough of it.
