Starlink isn't helping helping Ukraine out of the goodness of Elon's heart; he's being paid millions of dollars to provide a service. It's just another business deal for him that he can spin into good publicity as well. His public comments have made it very clear that he doesn't care about the Ukrainian people. Given that he's co-leading an administration that is completely aligning itself with Putin I don't expect that to continue for much longer. As soon as the payments stop, and possibly even sooner, that service will be gone.
