This Internet Explorer usage falls below 50% is actually big news and good news.
Over a few years the market share of the "other" web browsers has rocketed. That process was really started by free software by Mozilla (now Firefox) while others have come on board more recently, notably Google with Chrome.
The effect has been good for everyone. Internet Explorer has been massively improved in recent years and is becoming far more standards compliant.
Free Software is good for everyone, even those who never use it.
