I could see the cost to de-ice at an outstation like VLC being high - they probably don't stock much Type 2 and almost certainly no Type 4.

During the night, this enabled ice to form on the wings. The other aircraft may have had less fuel onboard, and were thus less susceptible to ice build-up.
The rules are more or less the same for all well-regulated airlines, as everyone's using the same reference material. Your were unlucky to be onboard an aircraft where ice had formed on the wings, the other aircraft you so taking off must have been clear of ice.
