1. Some of them show very poor communication skills or a lack of maturity — this has hurt bitcoin’s ability to bring new protocol developers into the space.
2. They prefer ‘perfect’ solutions to ‘good enough’. And if no perfect solution exists they seem ok with inaction, even if that puts bitcoin at risk.
I get this bad feeling that someone (author of the article) is planning a takeover and for all the wrong reasons. I've seen this "yeah they are smart guys, but they are introverts and our business needs to be extravert and agile and adaptive and fast moving and all other buzz words", then you introduce some of thous extrovert super agile people who just want to "bang out a solution, since any change is better than no change". Next thing you notice is that the old core team members are leaving after their protests about future of the product fell on deaf ears and these new guys are just pushing their own agenda/vision. Fast forward few years and just 1-2 or most likely none of the original team members are there anymore and cracks start to appear and these cracks are because the "better than nothing" solutions back in the day are found after all flawed, but now you have a lot of work build on top of rotten foundation and since your team now consists only of short sighted: "just fix it" people they are going to try to fix the problem at the top instead of at it's core "because we can't hold bringing in new features".
