We've all been there. Your phone is full of pictures stretching back 12 years to your very first smartphone. You try to plug the phone into your computer with a cable to clear space, but it ties up your device for hours. One tiny random error midway through, the transfer crashes, and your entire data set is left broken and useless.
So, you give in and download their cloud desktop application. Suddenly, that piece of software starts aggressively syncing every file back down, completely filling up your computer's local hard drive. You sign into your iPad with the same account, and now your personal data is forced onto that device, too.
The trap is set: they throttle your storage, charge you a monthly fee to keep it, and make sure you can never truly get your files out of their ecosystem. Ever.
