Maybe it's better to ask how they got it right for so long. Core has grown bitcoin from a small project to a $2 trillion asset, and with that comes many pressures. Just as no one person can get it right every time, similarly the group-think can have blind spots. It is often ego related, and sometimes agitation driven. Core is about to make a big mistake if they release v30 next week in current form. Fortunately, the community is communicating this loudly and clearly. If all else fails, it's open source, and we can migrate to new software and thank Core for their amazing contribution to bitcoin.
