I don't know why people allowed this transition from software ownership to subscription to happen (although they really weren't given the choice). It's ridiculous that the customer is giving away his MS Office ownership in exchange for the marginal improvements that MS has been doing in the last couple of releases.
Most people here on HN (me included) would benefit from this development but I agree with you: subscriptions are immoral.
PS: IntelliJ IDEA it's great but it is ridiculously expensive imho.
