The same reason is wrong to require a Google or Apple phone to exercise basic civil duties within government services. You are gating the service, or information, behind a 3rd party ToS, a login, and basically stating that you are not allowed to have it until you hand over personal data to such companies.
Why is it wrong? Is it wrong to require people to use certain tools? I don’t think so. It’s the same thing as requiring dress code to go to the tribunal or anything formal.
People here overthink so much about this topic.
The comment I replied to said "large companies", not government, and I don't see the equivalence.
