It really isn't. You're acting like the assumption of him committing DV is baseless, which sadly, it clearly is very much not.
And you’re acting like he’s certainly guilty, which is factually incorrect.
Imagine if Depp / Heard never went to trial due to it being a weaker case than it was - what would your view of Depp be?
Applying generalised DV stats to a person / family whose case didn’t even get to trial due to ‘new evidence’ is obviously not really a fair logic - just as presuming him ‘definitely innocent’ and would be.
This is what turns the topic into a perpetual motion device - the not knowing. For many people, not having the ‘explanation’ that caused the case to be dropped provided to them simply isn’t enough. They view it, either consciously or subconsciously, as their right to have this info.
And without getting it, it seems to make people lash out at those who don’t share their stance. Possibly because, for those that view MG as guilty, the whole process of ‘justice’ has just ‘stopped’ after going so far - there’s no conclusion, there’s not even an explanation.
So the ire starts to turn outward, at those who aren’t equally convinced at his guilt. It slowly becomes acceptable to call other people ‘r*pe apologists’ if they’re not convinced of his guilt (despite the fact he was never actually accused or charged with r*pe), and making horrible jokes about the disturbing topics involved is totally ok, as long as you do so on the side of presuming he’s definitely guilty.
