What the hell, I'll join the fray.
Wasn't Dottovu already doing a fair share of roommate activity beforehand though? Even if it was significantly decreased she still did some things such as post videos, join streams, host streams, etc. This is also true for Irys.
It wouldn't be the wisest thing to break the contract, but "only a little bit". So what could potentially be new that she could do now that she wasn't able to do before? Are we to believe they were previously breaking contract, but it was only minor breaches and so infrequently that Cover didn't care, but now that they can alter their new contracts they are able to actually consistently do actions that would have otherwise been a breach in the previous contract iteration?
On the side note, finally some good fucking rrats that doesn't involve shoving dicks in toilet paper rolls.
