Any faction created after the datacard handout (which was a one-time deal shortly before production, not something that occurred on an ongoing basis) should have been well aware that they would not get any datacards. They knew full well what they were getting into when they created the faction, and some have made themselves successful despite that. Others simply whine about the problems caused by their own lack of planning.
Factions without datacards can negotiate for datacard use with the existing datacard holders. No special provision needs to - or should - be made for these groups.
