Whilst I agree with what you're saying in premise, I think if you told most consumers "hey, when you have bad reception like at a stadium, your provider will connect you over WiFi instead of 4G", they simply wouldn't care and more importantly wouldn't want to know.
This probably is "consumer-friendly" in the sense of "provides the outcome desired for most consumers".
Sensibly and originally the consumer-friendly term is desirable, also the obvious and default behaviour from providers selling products to users.
Unluckily it is over and misused for things forced through regardless of wanted or not - but benefitial for the provider for sure -, being a routine misdirection (basicly bullshit) text.
