That's a different question. Team orders used to be against the rules (and teams were penalised for using them). For whatever reason, the FIA decided to start allowing them. The teams, and drivers, have to work within those rules. Vettel didn't follow instructions from his boss, and even deliberately ignored them. Any other job, that would be a disciplinary, no different here!
If you don't like the rules, watch a different championship!
