Fees for removing ETH from staking

I've been staking ETH on coinbase wallet. Previously, I'd been staking it on kraken. For one reason I'd another I needed to separate it out and I moved it over to coinbase.

On reading their staking FAQ, they claim that unstaking ETH incurrs a charge.

Coinbase charges me 0.6-1% to unstake my assets. Kraken charges me nothing.

Coinbase calls this 'network fees'.

Yet when I carry out this same transaction on kraken, it costs nothing.

Are network charges made for removing an asset, in this case, ETH from staking?
