Heh heh... so you believe three different influencing skills (Deception, Intimidation, Persuasion) should all be combined into a single skill, but yet the three wilderness-based skills (Animal Handling, Nature, Survival) all should remain separate? That is certainly one way (and a valid way) to look at it for yourself... but it doesn't then follow that other people are wrong for believing in the opposite combinations.
As I said, deceiving, intimidating, and persauding, are all forms of influencing. You want to get them to do something or believe something... in other words: to "go your way." Which is why they are all also Charisma-based. Even the text for Intimidation and Persuasion both begin with "When you attempt to influence someone..."
Athletics (climbing, jumping, swimming, and even grappling in combat), while all "physcial", involve very different forms of movement, but are grouped together.
Meanwhile, the three "wilderness-based skills" which you lumped together all perform fairly different functions:
Nature. Your Intelligence (Nature) check measures your ability to recall lore about terrain, plants and animals, the weather, and natural cycles.
Animal Handling. When there is any question whether you can calm down a domesticated animal, keep a mount from getting spooked, or intuit an animal's intentions, the DM might call for a Wisdom (Animal Handling) check. You also make a Wisdom (Animal Handling) check to control your mount when you attempt a risky maneuver.
Survival. The DM might ask you to make a Wisdom (Survival) check to follow tracks, hunt wild game, guide your group through frozen wastelands, identify signs that owlbears live nearby, predict the weather, or avoid quicksand and other natural hazards.
Of those three, the only overlap is recalling lore about the weather and predict the weather. There isn't enough overlap IMO to warrant making all three into one "Wilderness" skill.
So, yeah, I do think someone would br wrong for combining those three skills into one (just like I think someone trying to use Acrobatics instead of Athletics when climbing is wrong). A knowledge skill is very different from an application skill. Now, given the synnergy between them, I could see someone who had more than one skill given advantage in using the other. For example, a Ranger with Nature trying to recall lore about some beasts would have advantage due to also having Survival (but would roll INT). Trying to track an animal with Survival (rolling WIS) but knowning some lore about the terrain (Nature proficiency) would also grant advantage.
But trying to track using Animal Handling or Nature? No. That is Survival.
Trying to get a guard to let you pass? Do you want to lie to him, convince him, or threaten him? Whichever method you use they are all Charisma and result in you influencing the guard to do what you want.
Finally, I can think people are wrong. They can think I am wrong. I have no issue with disagreements.
