new software ruined my iPhone 6s plus

I can’t shake the Feeling that Apple is vindictively forcing us to throw away our “not cheap” devices to upgrade each year to keep up with software. Frustration is an understatement when it affects your work, correspondence, and well...life. If your software breaks down devices, then you need to provide a way to restore those devices back to the state they were in before we were coerced into “upgrading”. An upgrade is “by the book” something that promotes betterment, and progression, not regression. You successfully “downgraded” the productivity of my device. And I will not be purchasing a new Apple device with the fear that money is being thrown down the drain.
