If someone wants to kick you out of there house for no reason, you leave their house. You're not paying to be there, you're not paying to publish there... you have no intrinsic "right" to be there... you were there as a privilege - when it disappears, for whatever reason, there is no reason other than a false sense of entitlement to whine about it...
It's not a huge amount, but you do pay to be there. See https://developer.chrome.com/webstore/publish
"Before you publish your first app, you must pay a one-time $5 developer signup fee"
