Gee it sure is a good thing that I never even hinted at that then, isn't it?

Make me understand how I'm misreading the following posts, devoid of saltiness:
You: "The PHB gives the impression that the animal companion will be fighting alongside you!"
Someone Else: "They do fight alongside me; here's some practical applications that aren't necessarily standing toe-to-toe with me that I've seen an animal companion provide assistance in combat"
You: "Not standing toe-to-toe I guess that means literally they're not fighting alongside you."
Me: "That's a pretty literal application of a term that I doubt was intended as such. I mean, I 'fight alongside' my buddy's Wizard."
You: "Wizards do so much! Are you saying that's anything equivalent to a beastmaster's companion?"
Me: "I don't really think a beastmaster's companion
should be anything equivalent to a Wizard or other PC, do you?"
You: "I never said they had to be!"
I'm just really struggling to figure out where the goalposts on this particular point are when you keep moving them.
I'm not saying that
you or others didn't have a different expectation of ranger companions based on either previous editions or particular bit of lore; but it's a real stretch to say that the 5e PHB reflects that same expectation.
