Bitcoin Core nodes propagate blocks and transactions to all their peers, not just outbound ones.
And if you have 16 peers that getpeerinfo reports "inbound": false for, then all 16 are outbound connections. Presumably you're using addnode functionality, or using modified source code, as Bitcoin Core itself will not make more than 10 automatic ...

The nodes run software which contains the best-for-everybody rules about how the network should operate. One of those rules is that nodes should forward new transactions to other nodes.
There is no incentive for them that I know of, other than, to not do so, would risk not participating in the network of nodes that do follow the best-for-everybody rules. By ...

Can you reach anything over I2P? For example, can you browse http://git.idk.i2p/ using the router's http proxy?

It sends exactly one block. If you want to send multiple blocks, you need multiple messages.

Given that the vast majority of nodes are Bitcoin Core and segwit capable, this is probably okay, but technically does not follow the protocol.
Bitcoin Core itself does not check whether a transaction it receives is in response to a particular getdata, and so it does not check whether it asked using MSG_WITNESS_TX or MSG_TX. So responding to a getdata ...

There is a distinction between miners and nodes though miners will (or at least should) run a full node to check that the blocks they are attempting to mine are valid blocks. I think you are using the terms "miner" and "node" interchangeably here. There are many nodes (majority) on the network that just validate transactions and blocks ...

You can to a limited degree with custom software, but ultimately the data you would get is noisy and not particularly useful. A number of years ago I was crawling the Bitcoin network to get estimations of the speeds that nodes could attain by connecting, downloading a known quantity of blocks, and measuring the time it took. This makes assumptions about the ...
