Lijun Pan was listed in MAINTAINERS for IBM's VNIC driver with their IBM email up until 3 days ago, when they changed their email to their personal address and changed themselves from M ("Mail") to R ("Reviewer")[0].
Then, today, they received these instructions: "Please remove yourself completely from the maintainers file. I grant you a 1 time exception on contributions to VNIC to make this change."
It looks to me like there's been a change in the organization--either in this employee's assignment or in their policies surrounding contributing to their VNIC driver--that this employee was trying to bypass by identifying their commits as now being part of a personal hobby.
