My issue with that Gentoo is doing is that they are not making it up to every single node operator, they have made it the default policy.

I did a emerge -u world which updated my bitcoind and bitcoin-qt and I only found out that I got this patchset when I looked in the log and found entries about "blacklisted transactions". I would still have no idea if I had not looked in the log and actively taken action in order to not get this patchset.

I was indeed duped into running this code.

I am fine with people having a choice, that is what Gentoo's USE flags are all about. Making it the _default_ behaviour is making this choice for you.
