I can see a weird sort of logic to Apple. Why would they share their judgement about the level of an ex-employee with a potential rival company (rival in case of talent perhaps also product)? Let the employee say "I was Level 5 @ Apple" and have the hiring company verify that the person is at whatever level that implies. Why should Apple allow its rivals piggyback on its own levelling system?
Counterpoint: accurately ascertaining an engineer's capability is their secret sauce, why should they be obliged to share that information with anyone?
If that were really the goal then they would never publish the information in the first place. Instead they are apparently scrubbing it _after_ they leave. That's not preventing another company from using the data when hiring you away, that's being petty and erasing you from their history for the most part.
Who's publishing it? Apple is not sending out a list of who's at which level. You need to bring evidence if you're claiming otherwise. Products like Work Number are based on inference or direct observation of these titles through payroll integrations or other exhaust.
You are mistaken: Apple is not submitting that data, that's not how these products work. These data products are collected via scraping, other software integrations (e.g. payroll), or sometimes calling for employment verification, not from first party submissions. An accurate org chart of a company is valuable private knowledge, no company is just exporting it so that anyone with a few thousand dollars can get a copy.
