I have a feeling that the people posting here on HN that are against the subscription may only be a small percentage of their user base.
Personally I don't upgrade - because I don't need to. But if given the subscription I probably would if the price was right. Take Office 365 - yeah you can pay $200+ for a full offline copy but you have to do that for every version (and the whole keeping track of your media). Or just pay $99/year and get a perpetual license + extras + online installer. I know there are a number of people who are like "open office does everything I need!" - and that's great but just wait until you need to work on a document with another person who is using office 20XX and open office doesn't support the subtle formatting in that version yet. I know of a large company that tried switching to open office - they couldn't do it because open office didn't format many documents correctly.
