What I have been unable to establish is what those who run internet sites gain by making them inaccessible to older versions of browsers which work absolutely fine up to the point of site updates. Is it perhaps simply the case that they have no say and perhaps no understanding of what is going on ? Are the big operating system firms (Microsoft, Apple, etc.) simply offering only newer versions that deliberately lock out older versions and thus force the consumer to update, at a price ? Some people need the features found in new operating software but huge numbers of people have absolutely no need for them. The practice is perhaps akin to introducing a new fuel every few years, one which then works with new cars but not older ones and then the fuel stations increasingly provide only the new fuel.
