The heart of the 'collision model is broken' argument always seems to involve 'I did this while the other guy did that!' when in fact neither player knows the precise timing of what the other guy did, their intent or the amount of potential lag involved.
I think this is one of the few things that HTC should explain in detail and post somewhere on the forums (like the rules are at the top). Except it would be under a new tab.
Then showing examples like fugitive posted, etc. (or one of my videos showing a bomber dying from me, and then lagging backwards causing me to collide and get killed)
That way posts like these aren't made, so players aren't mocked for 'asking a question that has been answered # of times" etc.
Just a thought.
Happy New Year
