An oat drink is even less tech-oriented than Tesla. I'm not sure in what universe Tesla is not only not a tech company, but so un-tech-like that they're closer to a drink company, but I don't think it's this one.
Vehicles have air conditioning but that doesn't make motor companies appliance companies or HVAC companies either.
It depends on what the company's core value proposition is. Toyota's is clearly a car company. Tesla is now more of a car company, but there was a time when they had no or few cars but still had the battery and driving tech. Their valuation and promise was of bringing a new technology to the world, rather than a physical product.
