Is OTHER wrong in the post ? POST : So I saw reddit posts on this a while back actually. Some mom was doing something very similar and she was called an abusive parent. Just like some feedback for myself. 

I'm a single mother with 2 kids (12F, 15M) and the older one has had some issues with video gaming and internet use which heavily affected his grades. So now I have a system where the internet is always disabled right when they get home. They leave their smartphones downstairs and they have 2 hours after school each day to finish their homework. Once they're done, I reactive the internet and they can do as they wish. 

I thought I was being responsible with this. Before, I'd frequently find them both surfing instagram or social media while they claimed to be working on homework. Now I know they're working because they show me the work and I can at least be satisfied that some things are being completed. My younger daughter is ok with this system although my son has argued that I'm too controlling and even "abusive" for limiting his internet access. He says internet is basically a right and I can't restrict and isolate him just because I don't understand. But the thing is before I implemented this system he was making constant Cs in school. He played online games all night or would just chat with his friends. Now he's actually completing schoolwork. 

AITA for enforcing this rule? I was surprised when I saw similar situations pop up online and people saying the mother was abusive for limiting internet. Is this really the case?
