Miners Right Now
There is a big debate on how Bitcoin transactions should be processed in the future and the result is a power struggle between different groups of miners (those who process transactions with computer hardware) and software developers. There are some tentative agreements right now between some parties but not others.
This is poking fun at most miners implementing a recent compromise with the expectation that it will lead to more changes in their favor (one of potentially several to come).
That's my ELI 5 attempt.
