I encounter this type of issue all the time. People have different takes on it. Some are interesting, most are just selfish; ‘I’m inconvenienced and thus this is an outrage.’

But, I’m interested to know who’s really “at fault” here. Is it:

a.) Android for not allowing/enabling backward compatibility.
b.) Casper’s fault for not continually upgrading an already working product.
c.) The consumer for expecting a totally new hardware and OS to work the same as the old.
d.) the consumer’s fault for ever buying a cloud tied product.

I’m interested in everyone’s opinion.

You can most likely use apps like APK extractor on your old device to get the APK file and then install it on your new device. May or may not work depending on how the app was made.
