Sure, but eBay should be able to inform their members how to comply with regulations they themselves are obliged to enforce. 

The only reason I know as much as I do about it is because another platform who had to implement the same requirements:

Announced the changes in a way that couldn't be missed (i.e. a big banner on seller's home page)

Provided information on how to comply

Linked to resources to find out more

And then it became a collaborative community effort as well, where people researched, shared more resources, and other information from their own experiences... kinda like how forums like this will do that, occasionally. 

eBay hasn't even made an announcement, near as I can tell (the EPR thing for France started being enforced by marketplaces Jan, 2022, Germany was earlier, it should not be "new" to ebay).
