What’s the deal with callable CDs at high rates?

I see a lot of new issues cds that are callable at rates going up to 5%. Non callable much less.

If the idea of callable is for the bank/issuer to just pull the rug and stop giving interest once rates go down, why are there so many? Why so much supply of these compared to non callable?
Do people buy it with the idea of being ok once it gets pulled? Or are these sold later at a secondary market for a profit?
