Geez, Newbie. It's a trivial matter to turn off the I.P. "blacklisting". It's just a feature for nodes that don't want to deal with slow-ass onion routing.
These objections to larger block sizes seem disingenuous. It appears to be just a miner power grab, and a wrong-headed one at that. The real way to create a market for miner fees is to expand adoption, not squeeze the current users.
Agreed. But miners are pro larger blocks (The chinese miners got together and proposed 8 MB some weeks ago).
Only some of the Core devs are against. And probably some hidden interests, like banks, Visa/MC or Western Union.
