Hard evidence, anyone?
'Canonical is involved in a project to ship millions of PCs pre-installed with Ubuntu out to rural communities....“Who knows what the people who get these machines will do with them,” George says'.
Well, instead of asking "Who knows", get back to us in ten years and let us know. Better still, since Linux has been around for twice that long, please point out the persuasive examples which show clearly the fatal error of depending on "proprietary" software. Instead what we hear is mere speculation.
It seems more likely that proprietary software does well in the UK because we can afford it, while the "Chinese rural communities" cannot. Using "open source" software might not put them greatly at a disadvantage, but neither will it turn them from necessity into soaring eagles of computer technology, any more than the quirks of my car will push me to redesign it and hence forge a new automobile industry to rival Honda, Mercedes and the rest.
On this PC I use the latest version of Open Office, but it is, frankly, inferior to Microsoft's Office 2003 which I use on another. As someone who has done little but work in software for 30 years, am I tempted to take out the Open Office gearbox and change it to suit my needs? I am not. Microsoft Office and Open Office are just tools I use on the way to somewhere else. They both have faults, but I am no more tempted to fix one than the other, simply because I have access to its design information.
