RE: Proprietary Linux software: A big dilemma for many Linux users
I play music, I go out to hear live music, and I don't go to ballets with recorded music or patronize DJs. That doesn't mean I would refuse a wedding invitation if the reception had a DJ. Likewise, I like the concept of Open Source, but I'm not going to run an inferior video driver when I can get a good one from the vendor, nor am I going to pretend GIMP can do what Photoshop can.
I'm in business to help my clients operate their businesses efficiently - to help maximize sales and minimize costs. That could mean running Drupal on a LAMP server running Ubuntu or CentOS, all free both as in speech and as in beer. Or it could be Microsoft Office, QuickBooks, or AutoCAD because Open/LibreOffice is very good but not necessarily as productive as Microsoft Office and not quite compatible with business partners' .doc(x) and .xls(x) files; and nothing Open Source can hold a candle to QuickBooks or AutoCAD.
