However you can’t ban advertising online. it’s how operators pay for their servers.
And how do you think John Deere pays for its servers?
No, not by ads, but by locking down their software such that only those who pay a fee to enable the features which rely on those servers are able to use those features. Right to repair is seen as a problem for them because it would open up the software configuration, allowing enabling of those features without paying the fee.
Right to repair trusts that actors will act in good faith and pay the fee, even if it can be technically avoided. Why can’t ads go the same way? If you opt-out of seeing ads then surely we can trust that you will pay the equivalence by some other means?
