I think it is kind of levels:
"can't participate in society without a mobile phone" "can't participate in society without internet" "can't participate in society without google"
not sure where is the logical correct threshold making it wrong. because we all accept maybe people not participating without internet.
I don't think it's an issue to require Internet to participate in society, just like it wouldn't be an issue to require a mobile phone if you can use any phone (including a Linux phone or degoogled Android).
The problem is that now you need a phone with Apple or Google software running it.
> not sure where is the logical correct threshold making it wrong
This can't be more clear: Forcing to use the duopoly is against the competition and is totally wrong.
Clearly the logical threshold is when a single private corporation becomes the gatekeeper to your life. The internet itself is decentralized so that's fine. Mobile phones as a concept is also fine.
