• "Kinder than necessary" can go a little far sometimes. It can inadvertently stifle honest conversation. That said, it's better to be too kind than not enough.
• Tech stack is outdated. Duo is making a concerted effort, but it has a ways to go. Still a VM architecture. Some services have been containerized, but they aren't container native.
• Not diverse. Though that's an industry-wide problem. The culture is inclusive, so I'm not sure why diversity isn't higher.
