These ones cannot. But with intersat optical links, it'd be perfectly feasible to have some percentage of sats as part of the constellation in the future that talked up rather than down, using either radio or optical links themselves (no atmosphere to worry about obviously). No need to have any single satellite do it all. If commercial satellites could simply plug into Starlink in a standard fashion and then it's normal internet from there, no groundstations or any other infra to worry about, that itself would be a big deal in terms of further removing obstacles to wider spread commercialization of space. It's something I haven't seen considered much but I think is another really exciting example of how many things SpaceX is shifting in concert and finding self-reinforcing effects for. Scary thing to be up against though for competitors.
