I think it's more like - you're looking to charge your phone at an airport. You're a Samsung user and you bought a contract to be able to use special Samsung-provided kiosks, which used to be an exclusive feature for you.

As you look for a charger, you see a dude with an iPhone sitting across 2 of the charge stations. (Maybe there's only a couple other stations free. Idk from the article). You don't realize that Samsung recently opened the chargers to iPhone users.

You're also irritated because it's been common for people to be assholes and doing things like leaving their phones plugged in and hanging out for hours. Way linger than they need. Or people sitting at the chargers who are just waiting for their planes and not charging at all. So youre sensitive to people you perceived as being assholes and making it harder for Samsung users to use the service they paid for.

Tesla dude was clearly overreacting, in the wrong, and being a douche. At least, based on this one-sided ragebait article.

But I was mostly replying to your Coke vs Pepsi article, where you were making it sound like the Tesla guy was mad at the other dude simply for buying a Rivian.
