The timeframe is often quite different: Google gives you 12 months notice before turning off the lights. A FOSS tool "forces" you to upgrade when the old version you're using has a serious security issue that's is not backported. Which means that unless the supported version is fully backward compatible with your software, you have a quite tight schedule to deal with. Sure, you always have the "option" of running insecure systems. Unfortunately a lot of people choose that "option" and severely underestimate its cost...
