I just had a chat with Sharn about this - our non-negotiables are probably:
- Steam (a gaming platform where we have purchased thousands of dollars of PC games)
- Discord
- YouTube / YouTube Music.
We can live without the others. The thing is, we're not children, and our accounts on some of these platforms are >16 years old anyway!
Oh, wow! I'm pretty sure my accounts aren't that old, so would require further proof of age. It will be interesting to know if they still try to require proof of age from you, though.
