This is very mild. Cases that have affected me: 1) Augmentra made a mobile phone app called Viewranger which is useful for walking. It presents topological maps, and uses GPX files to plan a route or record a trail. I bought the 1:50000 maps for the whole of the UK for about £200, plus various other maps over the years. All of these were lifetime licences. Augmentra decided that they wanted to be rent-seekers, and brought out some similar software with a periodic licence fee. No problem there. But they also pushed out an "upgrade" to Viewranger which disabled it completely on a certain date. That's theft, to my mind. 2) TiVo in the UK used to sell one PVR. You could pay a subscription for the TV schedule which you needed to make it work effectively, or you could buy a lifetime subscription. A few years later they wanted to bring out a new model, and they shut down the data feed for the old model. 3) Garmin satnavs can be bought with lifetime map updates for particular areas. The problem is that with older models they used a proprietary protocol to get the data in and out - and that stopped working. Look it up on the web site and they claim that the problem is the increasing size of the map data, and that the older models don't have the space. No, there's plenty of space, you're just not honouring the deal. And we're talking about an expensive weather-sealed motorcycle model here, not bargain basement.
