Article 5(1)(f) of the General Data Protection Regulation (GDPR), in common with existing data protection legislation in many jursidictions, defines requirements for accuracy of personal data. If the job title that a person held is regarded as personal data then Apple is in breach if it changes this data to something that does not reflect a true value and, worse, then exports that data out into other systems.
Is a job title personal data?
Article 4 of the GDPR states: "‘Personal data’ means any information relating to an identified or identifiable natural person (‘data subject’); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person."
Further:
"This element is very inclusive. It includes “objective” information, such as an individual’s height, and “subjective” information, like employment evaluations. "
So, in Europe, UK, Australia, and New Zealand (at least) this action by Apple appears to be illegal to start off with, and becomes doubly so if Apple refused to correct the mistake when asked. I'm not familiar enough with the US to know if it cares about data accuracy versus $$$.
