Big companies stop working. Maybe they got too big. My usual example with Microsoft: their operating system and office software got better all the way to 2003, then everything started to get worse. Their changes started to make some things better but a lot more things worse. Or look at the US government: it started out as the best democracy in the world, and in the last few decades, it's been increasingly turning against the world and against its own citizens, too. This might be happening with IB as well: economies of scale gone wrong. They did great, got big, developed a huge structure, and now the structure has to do something, such as... even creating problems so it can solve them. It's like the false-flag attacks of 911: the developers are now creating "false-flag" bugs so they will be given the task of solving them. If everything is perfect, they'll be fired, so maybe they don't want everything to be perfect. Just speculating, but there might be some truth in what I said.
