I disagree. This is far from cost-effective if you go beyond the simple "build a simple app" as the article is about. The costs (= time spent) skyrocket when you have to include CI/CD, and real debugging (starting with, say, breakpoints), and not talking about the always-present last tiny bits of things you have to do specifically for each platform (Info.plist, Build Settings, build.graddle...).
The "one-time development" promise is a false-promise to me. The promise is valid for some code. But you need a LOT more to make a real production app.
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
