I dont know about that comment that they make "they waste helium, a finite resource". It's not as if there are helium mines that are running out. Helium is extracted from the atmosphere, and then it goes back into the atmosphere when a ballon deflates.
Actually not , The primary source of He these days is Natural Gas production, Another major source of He was weapons grade plutonium production since that stopped there has been an increasing shortage of high purity He for industrial use in the US.
