Perhaps this is a carrier-imposed or controlled restriction, but if that’s the case I can’t even begin to fathom
why, so I suspect it is Apple. Quite frankly it’s ridiculous.
I have 50 GB of mobile data available and can blow through it all on 1080p television or movies in no time if I want, but they won’t let me download a piddly little 150 MB app or app update!
It’s 2019 already, I wish they’d just get with the picture! Data is data; or is Apple pro data-discrimination?

It’s things like this that add up and make me question whether iOS is the right platform for me moving forward. Hasn’t the 150 MB limit been there forever; since the very beginning maybe? Like what the AF Apple!
This defence makes no sense. There are no limits (and possibly not even any warnings) if I want to download or stream a 6 GB movie I bought or rented from iTunes. Further, there are many ways to obfuscate the option to unhinge the cap for data-rich users that still protect the stupid. Make it a setting hidden or buried deep within Settings, or require double or triple confirmation!
Apple hides behind reams of T&Cs all the time and allows you to proceed when you clearly haven’t read them. I don’t buy the “they’re protecting the masses” argument one bit.
150 MB in 2019 is archaic. At least make it 500 MB or 1 GB with the option of no limit whatsoever!
