Try not to take the insults to heart... nasty people often lack objective thinking and feel safe to hurl insults online.... akin to online bullying and trolls.
Your DM hasn't taken her own wellbeing and support/relationships into account...which may be perceived as selflessness by some, but ultimately, the potential impact on her mental wellbeing is highly likely to negatively affect her.
You have your DH and DC...she's the one who will be alone and may well live to regret her decision, if your relationship doesn't go back to what it was.
Making these decisions should take all factors into account, especially where it can affect those who are an integral part of your life. If you were not so close and hardly saw her...then it wouldn't be an issue.
I agree with the pp who mentioned your mum's age... However with a shortage of foster carers...sometimes they just have to go ahead, even if it's not the ideal placement/family set up. It will be like living with a grandmother for him.

Actually it sounds as if the OP's mum is really struggling, and isolated. She desperately needs respite care for her foster son so she can have a break
The OP has said respite hasn't worked out due to his behaviour/complexities.
She probably should have realised after many years of fostering that while she can choose to take any child placed in her care, that this will impact on her, as the OP and other family members who have previously been able to see her/ support her, may no longer be able to.
now your mother is mostly isolated from the rest of the family because of him - but obviously she feels that it's worth it
Yes.. but her mum saying the OP is unreasonable for not going over with her DC is failing to understand her daughter's position and need to safeguard her DC. She's made her decision to keep the placement...she doesn't get to force the OP to comply with what she wants.
