The only thing specifically related to Ukraine was Ukraine (specifically their minister of digital transformation) reaching out to Musk via twitter.
Both could be countered by a sophisticated adversary, but the Russian troops may be a little preoccupied at the moment, and their EW teams are probably going to focus on Bayraktar before Starlink...
Starlink have already enabled "Roaming" for Ukraine which involves similar tradeoffs: https://www.youtube.com/watch?v=8PDVURcvWeg (in fact I wouldn't be surprised if the changes enabled for roaming also improve jamming resilience)
Meanwhile, I assume it's far easier to take out Starlink than Bayraktar. In no small part because interference was part of the threat model when Bayraktar's hardware and software were being designed. And they can get a lot of results for less effort with Starlink.
