Even if the rest was vague enough (and it only would be if this was a very common set of experiences), there was a screenshot of a 1-on-1 meeting time and room, so the anonymity ship has sailed.

The meeting was deleted afterwards. It’s mentioned right there in the post.

The main villain - the sr. director with bad breath - predicted this and got his subordinate - a manager - schedule the meeting. Later he stopped by and replaced that manager. In other words, he can claim he has never been to that meeting.

surely Apple could easily recover this information if they wanted to?

Logs

If this story realistically describes what happened, I would expect Apple HR can identify who wrote it (Muslim with a student OPT visa, specific request to do no previous work experience, reported issues with the export license, and a case like this)

If there were tens of similar cases, we would have heard of more.

Apple's culture of silence works well enough that employees are self-censoring. You do hear a few stories now and then, but often constrained to IS&T or from non-engineering orgs:

Someone has to speak out first and it has to get a ball rolling. Stuff like this can be hidden for decades before coming to light, if ever, see e.g. #metoo with prominent examples like Epstein and Spacey.
