Not that that made Tridge in any way deserving of Linus's ire ... but I guess Linus was upset to see his personal friend McVoy go off like this, and blamed who they saw as the instigator. Not the best reaction all told, but understandable human behavior regardless. Of course, the actually meaningful response was that he wrote Git, so it's all just ancient history now. I doubt there's any hard feelings left between any of the parties, or at least I like to think so.
You'd like to think so, but I wonder what McVoy thinks about it all. After all, before that, he had Bitkeeper which was his business, which had the distinction and fame of being used for the Linux kernel project. Now, who even remembers BK?
