I think you are missing one thing. HTML, CSS and ekhm EcmaScript are open standards not owned by any single corporation.
Every other toolkit was not gaining adoption because it was shut down by one or the other corporation owning one or the other system. GTK is mostly irrelevant as it doesn’t do mobile.
Web stuff is best we could get away with circumventing corporate greed and ownership.
Even if we nag technically it could have less complexity - in reality not because all it was required to work around corporate bullshit.
