Bitcoin Core Releases Bitcoin Core Development and Transaction Relay Strategy Statement

Bitcoin Core Project released a statement saying that Bitcoin is a network defined by its users, and users have the ultimate free choice to run any software they wish to use (with or without full verification) and implement any policies they wish to follow. Contributors to Bitcoin Core have no right to dictate what rules users must follow.
This principle is reflected in long-standing practice: Bitcoin Core software does not support automatic updates. This means that no entity can unilaterally force changes to Bitcoin Core users. All changes must be at the user's choice to upgrade to a new software version, or choose another different software. This freedom to run arbitrary software is the main safeguard against external coercion on the Bitcoin network.
"As developers of Bitcoin Core, we also believe it is our responsibility to enable the Bitcoin Core software to perform its core function of validating and relaying blocks and transactions in the most efficient and reliable way possible, thus supporting the success of Bitcoin as a decentralized digital currency."
In terms of transaction relay, Bitcoin Core may include some strategies, such as: denial of service (DoS) protection mechanism; fee evaluation strategy; but we will not block the relay of transactions that have continuous economic demand and can be reliably packaged into blocks. "
