How does BCH combat centralisation?

Hello,

I've been looking into why Bitcoin developers are reluctant to raise the size of the blocks and the main reason I seem to have found is that they want to keep the blocksize small to ensure enough people can run their own nodes and thereby counter centralisation of the nodes into the hands of a few corporate entities or miners who have the financial means to run said nodes.

Now this makes sense to me, bigger block sizes would equate to much more data you have to send and receive to maintain a node. Not only the sending and receiving of data, but there's also the cost of hard drives you need to factor in. If the blocks get big enough, the average person might not be able to run their own node anymore.

How then can BCH guarantee that the network stays sufficiently decentralised since they are using much bigger blocks than Bitcoin?

Apologies if this is a silly question but I'm a bit of a newbie concerning BCH and would love for someone to clarify this for me.
