Elon collecting signatures from demographics least likely to vote, or starlink being used in many districts as the network uplink for insecure machines

Are sources available on these claims, particularly the first one specifically it being the least likely voter demographic? I keep seeing this stuff talked about but also hand-waving that it’s been debunked and I’ve been too wrapped up with life to investigate. I’m not hopeful that credible and clear evidence will show up enough to get widespread attention about vote hacking but I wouldn’t be opposed to hearing more come out either.
