Sure, but the article also states:

"The U.S. Food and Drug Administration (FDA) last month decided it would allow sales of the IQOS device in the United States after a two-year review process in which Philip Morris repeatedly assured the regulator that it would warn young people away from the product."

I'm sure Phillip Morris made the FDA well aware of their "self-imposed" age limit when pushing for FDA approval. I doubt Phillip Morris introduced this age limit because they suddenly found their moral compass or started to hate making money. I'm sure they use it to get regulators off their back, so this definitely isn't a good look for them.
