If a company has a commercial software product using some proprietary

allow them to continue to sell their product just as they did before, or
does GPL then mean their entire product has to fall under GPL?
IANAL but it falls under GPL and that's why MySQL dual licenses their
product. Much of their business depends on this quality though there is
a good amount of support subscriptions being sold too.
