And for the Thursday TTTs, they just look at Zwiftpower and they don’t extract live game data from Zwift servers as rhey do in ZRL. That’s the key difference.
WTRL own the TTT, Zwift own ZRL. this is a child protection law issue not necessarily the sharing of data that comes with using WTRL systems.
It’s a bit of tricky question on what laws each individual organiser has to follow but zwift is global and has to consider and comply with multiple legal requirements in countries they operate.
I’m not sure what the correct answer for an individual organiser is whether they should be following what zwift do, apply local laws only or just put their head in the sand and pretend such laws don’t apply to them.
