not counting the “deferred revenue” line, which is not a true liability

It's not a true liability such as it owes that money to someone external to the company but it is a liability because it a charge against the asset side of the balance sheet.

If you decide to exclude or disregard it from the liability side it should equally be excluded from the asset side.
