I understand this from the point of view of increasing the fees to be distributed to miners but it seems like there is still a risk of hashpower canibalization between the main chain and sidechains or am I missing something? #Bitcoin #Bip300 #drivechain

Sidechains do not "mine" using hashpower. Every side chain block is mined by creating a single transaction on the main chain that pays transaction fees to main chain miners in btc like any other transaction.
Basically, if you are a sidechain , you build a sideblock by aggregating side-transactions, charging side-btc. You then turn back and offer btc to main chain miners for them to include a commitment of the block you just built on the main chain.
