Nowadays, half the software you interact with doesn’t even reside on your PC. Further, there are whole departments at, say, Facebook or Blizzard or Google whose entire job is to “enhance the user experience”. If they’re not constantly dicking around, adding and removing features, changing what buttons do, moving things around … then they’re not doing their jobs.
There’s one sort-of-amusing upside to all this: it’s tricky to pirate software when that software calls home every time you use it. Guys who’ve gotten used to reinstalling the trial version every 29 days are despondent; why, they don’t even beg for serial numbers anymore.
