My mom was. Very welcoming but very insecure around my father's side. Always threatened by friendships/closeness as if it was a slight against her or her side. But due to age differences and distance and finances, we ended up seeing my dad's side more, and she definitely resented it. I think I eventually learned to ignore it and not let it affect my relationships, but I dealt with years of guilt.
She does it with my inlaws now too, though not anything as direct or explicit as your mom. I do think you should try to talk to her once, but know that given whatever insecurities she's dealing with, this may never go away. You just need to set boundaries and let her deal with it.
I think some people have an innate dislike or even hatred for in-laws. Maybe it's even in their DNA. I know my own mother was this way. She has had something negative to say about almost everyone in our family who isn't "blood;" even her own sister in-law who she gets along with. I think she almost can't help herself. Some people just can't help themselves when it comes to in-laws. Maybe it is a sort of DNA survival competition or something. In my own family, I've been blown away by the competition and dislike and badmouthing I've witnessed.
