Concept of open source is commercially not viable. Creator of source code want recurring revenues from the work done once.

I've been using free, open-source software for at least 15 years now. The overwhelming majority of software on my computer is freeware. The company I work for recently switched from Microsoft Office to OpenOffice not only because of the price (free!) but because it is smaller, more stable, and provides better compatibility with other document formats than MS Office does. The decision was, without doubt, forced by the extremely high cost of upgrading to Microsoft's latest version. By deciding to switch to OpenOffice, our company saved at least $22,000 in software costs for this year.

Free and open-source software is good for you and for the world. This is the best Windows software that we know of.No adware, no spyware, just good software. View link: [visit link]

Most of the naysayers are too afraid of the prospects and deploy their arguments more as a wish that some day soon the old familiar paradigm will survive intact. If you have followed reactions from some who are amongst the staunchest supporters of Open Source, you will have seen the initial hostile dismissal, followed by increasingly mellow statements and finally the volt-face. Very early on I asked a number of them to write an article a year hence and I would remind them of the first one they wrote - I have never been disappointed, it took one writer just 10 months. Of course, the proponents of the old proprietary order are still there, perhaps never to be convinced - they have too much at stake to change their views, King Canute characters standing resolute against the oncoming tide, to be washed away and their words with them. My manager who tried giving me a hard time when I switched away from Windows to Linux at least had the humility years later to admit that he thought I was going out on to a slender branch which was already consigned to falling. I was even introduced to one of our customers as a "Linux Bigot" by one of our salesmen who had been asked by the customer to have someone give them some information on installing Linux on their mainframe. The undying truth is that whatever and however harsh the criticisms, Open Source developers keep writing code undaunted. My guess is they had a forlorn hope that the developers would realise they were on to a loser and redeploy their efforts back to proprietary code writing or to sitting in front of TV sets with cold beers instead. At best most developers were disdainfully regarded as college student type amateur software writers incapable of producing anything of quality, at least nothing that sould match the professional standards of proprietary products. Here in the UK, we were even called users of Boys Own Unix, a disparaging simile of a once very popular "Boys Own Comic" that has long ceased publication.
