I think when Congress eventually gets their collective head out of their *** and consumer "right to repair" (and modify, customize, retrofit, etc.) becomes law, you'll be able to do whatever you want with whatever you legally own as long as it does not violate other laws (ie, interfering with public safety communications, etc.). If they wanted to maintain complete control over their products from cradle to grave, they should have maintained ownership of it and only leased to departments, companies, etc. But that would have cost them more money to have longer warranty and service contracts, recycling programs, lost sales of the latest and greatest. You can look at all these software and programming "gotchas" and traps set by the radio manufacturers as a way of avoiding those responsibilities, but I believe in the end it will bite them in the butt and they will be forced to allow legitimate owners of radios access to tools and software and render some of the legal issues unenforceable.
