Is this odd?

Watched movie with new bf and I saw that he was logged into his exes streaming service…I didn’t say anything but I felt it was awkward as his gf to see he uses his exes stuff. He talked about her a few times before early on in dating, and now when I saw this it kinda makes me suspicious if he’s not really over her? They aren’t on speaking terms and spilt over a year ago but I find it odd that his ex is willfully paying for her ex and his new girl to use her stuff or that he’s simply mooching off? Again I’m not saying anything, but find it odd…it’s not that expensive to just purchase your own monthly plan for like $10-15 a month.
