It's nature Chris, and yes, it shouldn't be messed with.
The small silvers on my local are abundant, we don't get the floods we used to. So it is obvious the preds will flourish, it is selfish to think the preds shouldn't be there, it's nature at work.
You're right about match angling, it took a turn with the introduction of commercials. The rivers became almost devoid of match anglers (I'm not gonna rant, each to his own!).
I'm an all rounder, I love to catch silvers on the river and pike too. If a pike grabs a few on the way in, then I get the pike rod out.
Live and let live applies to pike too, it's nature.
