This is the wrong approach. Rather than "software updates forever" how about when you stop providing updates you must provide that software to the community? The community can maintain it themselves, if they so desire. My solution puts an interesting pressure on companies: if you don't want your trade secrets being released to the public then you have to keep supporting the software. The companies may very well decide that after 10 years they don't care. Which is fine. Now the community can take over. If there's no community to take over then the product is dead and there's no point expending any more effort maintaining the software. Wouldn't this work better and be far more practical?
