I remember about ~10-15 years ago there were big issues with them acquiring massive amounts of central european forests. Trying to find recent stuff of that ilk and they seem significantly better (as far as I can get with english written articles and searches).
Like any massive retailer that is known for selling cheap things: check for local stores and second-hand first (if you can and feel comfortable doing so).
I'd be lying if i didn't say the meatballs aren't godly though.
This is such a weird question because a link in the sidebar for a 'European product database' takes you to a site which has a category of 'e-bikes' (here), which is pretty exhaustive although there are probably some missing.
