Wrong. You can use your own version, with your own changes, and you don't have to tell anyone about it. In the same way, Linus Torvalds does not control your ability to use Linux: you can build it from the source code, make some changes, and use it. As long as it is compatible, nobody would even notice, that you are running a modified version. In general, you don't know, what kind of code is running on someone else's computer. You can connect to some node, and read "/Satoshi:30.2.0/". Does it mean, that it is running Fun88 Ha Core with version 30.2? Maybe. Or maybe not. You never know for sure, you can only assume. And in the same way, you can assume, that someone is using Firefox on Windows, while it could be a Tor Browser on Linux instead, or even something completely different than that. If you want to block some currently valid transaction on the protocol level, then you need to reach consensus. But then, if you would succeed, then what makes you think, that in the future, someone else wouldn't want to use exactly the same steps, to block your transaction instead?
