Eth is great as a developer platform, and it can/does have a future. However, btc will remain the true king because of its decentralized nature.
The entire point of crypto is that it tries to solve the problem with existing currency (fiat), which is too tightly controlled by a few individuals.
What I mean is, Ethereum Foundation or not, only some small set of people will have commit access to the upstream bitcoin repository. Additionally, because of economies of scale, it makes more sense to pool resources under one central roof to solve the proof-of-work.
There might be a convoluted and informal political process involved before merging changes to the protocol. Mining companies might choose to limit their size in order to protect the network and thus their income streams. But ultimately, the number of core developers and miners, i.e., those with real power, is much, much less than the number of merchants and users.
Nope. See below.

Ethereum has supposedly 34k nodes, which includes light-nodes which merely hold the last state of the blockchain, that is not a full-node and heavily reduces the trustlessness and security of a cryptocurrency. Light-nodes are closer to an SPV than a Node. I haven't seen any source reporting only full-nodes which would be the proper comparison.
On the other side the number ~7.5k nodes popup for Bitcoin, but that's wrong as well. Those are the full-nodes that are listening for new connections publicly. Not all the nodes of the Bitcoin network.
Following [1] you can see the data from a seed DNS node of Bitcoin, which shows a number closer to reality which is 86k of actual full-nodes.

That's a big statement. Expand on it.
