People absolutely lie about weird, tiny stuff online all the time, especially when there’s zero chance of ever being called out in real life. It’s not even always about “winning” an argument, sometimes it’s boredom, ego, wanting to feel intellectually superior for 5 minutes, or just reflexively doubling down once they’ve said something dumb.
So yeah, it feels odd because it is odd, but it’s also one of the most common things on the internet. You’re not crazy for noticing. So I give it a very small chance you are actually telling the truth, sorry not sorry been around this industry for 20 years myself.
