Your reasoning feels truly bizarre. He added that work email as a SECONDARY mail. As soon as it stopped working, he could no longer access the boards associated with that particular mail, only his personal ones that were NOT associated with it. His personal boards continued NOT being associated with that work email for years afterwards, and he never in any way indicated, asked for, or allowed that they should be.

HE didn't “plant a time bomb”; Atlassian ripped him off, plain and simple.

(Oh, sure, you could argue that he “planted a time bomb” by giving Atlassian the means — that email address — to rip him off... But please don't. That would be like arguing that a rape victim “planted a time bomb” be dressing too provocatively.)
