It's hard to take you seriously when you refer to a single individual giving away a huge chunk of wealth with no hope of earning a return as being an "industry".
Regardless, the man's $600 billion went to found a number of charities for the purpose of putting out anti-smoking ads in states across the nation. He is also rumored to have been a major contributor to "thetruth" (apparently, it's a big secret) who, despite the good that they do, were also filthy with misinformation.
You're not entirely wrong that one man doesn't make an industry, but if one man started 20 companies that all shared the same purpose, would that not constitute an industry? Maybe it wouldn't. Maybe I'm using industry wrong. Either way, I agree that I misspoke, so hopefully this at least clarifies my position somewhat.
