Can't speak for Hack Reactor, but your generalization of "bootcamps like" is wrong. Went to a bootcamp in 2016 and was doing React/Redux on the front end.

No, this generalization is quite correct. If you went to a bootcamp which was not such as Hack Reactor, then perhaps you may wish to promote the program by name and discuss your experience there.

I went to Fullstack Academy in 2017 and React and Redux were both part of the core curriculum

This is totally wrong. I hired a couple devs from Hack Reactor years ago and they had tons of lessons based on React and the ecosystem around it.

Your information might not reflect the online-only program, which is now the only choice. My information is from two sequential cohorts of students who are yet to graduate. Also, if you know what to Google for, then you can see how the curriculum has updated over time. Some students do this to cheat, and they can do so precisely because the curriculum is largely frozen in time.

Hack Reactor has made Redux completely optional and so almost nobody choose it for their projects. This may have been in response to transitioning to an online-only program. If students understand anything on the "React ecosystem" including even Redux, it is due to their own personal ambition. If you see Redux explicitly listed in their curriculum, do not be confused.

If you see students with Next.js, RTK, or any other framework or library from the React ecosystem on their portfolio, that is due to their own grit.
