Despite claiming he's no longer a Bitcoin Core developer Greg Maxwell is having a spat with Bitcoin Core developer Luke-Jr over TapRoot

1) Despite Greg Maxwell claiming he is no longer a Bitcoin Core developer why is he shaming Luke-Jr into merging a patch that he does not wish to merge? Why is Luke-Jr calling Greg Maxwell a liar?

2) Why is Greg Maxwell telling the /r/bitcoin what they must do in their subreddit? Why is a non Bitcoin Core developer(Maxwell) trying to get a Bitcoin Core developer (Luke-Jr) banned from /r/bitcoin? What influence does he have over the moderators in that subreddit?
