If Apple believe they can make a competitive product to Peloton (and I imagine they do) then the additional staff and offices aren't necessarily a good thing.

To put it another way: why should Apple buy Peloton? Apple itself is already a premium brand with huge awareness, so a buy for brand reasons isn't that persuasive. Peloton has a whole range of hardware but none of it is compatible with existing Apple hardware, so integration might be a drag.
