The problem is that product managers and management in general want features and don't care about technical debt.
So if you are working on a bug (fixing technical debt) then you are not working on a feature.
Also, working on features is often (but not always) more predictable in time estimation than working on bugs, which can be a completely exploratory task with the only endpoint being "it works now"...
