2017NOV14: How can I update to new IOS11, when it disables the use of hundreds of apps I purchased via AppStore and use daily? Currently using iPhone 7+ and iPad Pro 10.3.

Hello Apple Community: In good faith I have purchased hundreds of applications authorized by Apple for sale in the App Store, to be used on my Apple Devices, only to be informed with this latest release "IOS11" that these apps will no longer be available to use if I update my IOS. For years, the updated IOS has always been compatible with the hundreds of apps I previously purchased, now I am threatened with this foreboding phase "This app will not work with future versions of IOS. The developer of this app needs to update it to improve its compatibility." I have contacted a developer, and have offered to crowd_source funding to get the update for older apps, but it have not received a reply. This change Apple is making to ensure we always have the 'best-of-the-best' should never wipe out the use of honest purchases of previous software. I maintain my hardware to get the most out of the products offered, but never did I expect to do this at the cost of my software.
