I didn't know Target had a credit union. The two links about it you provided didn't have a lot of information though, especially since many are old (before the merge -now it's called BCU?).
You are correct about the new ownership.
Target credit union website: https://www.targetcu.org/home.aspx?mddov=''
Was purchased with credit card portfolio, last year.
Hardship has not changed, ck with your hr.
For additional info, ck your info board in your store, near your break room.
