My primary hesitation with posts like this is that it mixes engineering points (performance, developer experience, code sharing) with a more general business point: hiring.

Hiring is a cost. There are costs to any decision. Opportunity cost, risk, business continuity, operational costs, etc. Hiring is generalizable so it makes for an easy example here.

I would hope that experienced folks making decisions like "React Native or Flutter" would weigh the full gamut of costs in their specific business context.
