This basically means that everything that has software updates can be returned forever. It doesn't. It means that functionality cannot be changed in a degrading way, but upgrading and non-conflicting security updates are still allowed. For a customer, money upfront and money over time is the same (adjusting for the interest rate). They don't need just a dead brick, whatever it costs in production. When your saas stops having a feature, you stop paying. This is no different, except that I'd vote for a law which amortized the upfront cost to the real usage time. E.g. I bought a treadmill with 2-year warranty for $4000 and it stopped doing a claimed feature after a year (iow, became broken from my perspective). I either receive a service which returns the feature, or get $2000 back + 20% fine for inconvenience.
