Not my experience. It used to be the case in Windows 98 but I haven't found my systems to be slowing ever since I bought an SSD. SSDs solved all of my problems and they're rediculously affordable.
I also have a cluster of windows machines performing raytracing and other extremely performance driven tasks--I can't tell the age of an install based on performance.
This is all just superstition at this point without numbers. Yes if you install a third party anti-virus solution and you have a bunch of auto-installers running in the background your computer will run "Slower" than it did without anything running in the background but that's not Windows' fault and that's true of every operating system regardless if it's *nix or Win*.
Quick trip to a federal court for extortion.
Most United Frequent Flyer awards though aren't claimed though. Except for really popular routes at popular times you can get a Saver Frequent Flyer ticket almost anywhere. Your assertion assumes that Award tickets are always completely filled. Especially considering that most Airlines can now sell out entire flights most of the time that means they are missing out on some revenue.
Frequent flyer programs do cost money but they also do make a lot of money too. Both through Credit Card fees and because if you do legitimately concentrate on one airline you will spend a little extra for the miles. For instance I'll fly a preferred airline even if it's $120 more on a $1,000 ticket because the miles (Especially status miles) are worth $120. So not only are they making more on their sale than a competitor but they're making the sale in the first place. If you fly randomly on random airlines, almost nobody will earn enough reward miles on any given airline to ever redeem them at all.
Try 10 times and assume that there isn't a cap after that. Much easier on the servers than 9999 password reset attempts.
This is a huge security vulnerability and they should patch it. But he also blatantly broke the rules.
