React is close to an industry standard, sounds like bad management. Again, you don't have to know React to hire for React, just bring "smart and gets thing done" people onboard and trust them on their word that they can quickly learn anything they need to get it done. Clear responsibilities and goals, trust, swift consequences if that trust is breached.

Yes, I don't disagree. Well, it's a place where engineering has seized power through obstinance and used it to do whatever they find interesting or resume-positive. Luckily I'm just consulting here as a favor for an old friend.
