EDIT: Enshittification, also known as platform decay, is a process in which two-sided online products and services decline in quality over time. Initially, vendors create high-quality offerings to attract users, then they degrade those offerings to better serve business customers, and finally degrade their services to both users and business customers to maximize short-term profits for shareholders.
We do have an equivalent to Ada. It’s Ada. The open source GNAT compiler is actively maintained. Eiffel, too has a maintained open source implementation, but with a weird one-year release delay (probably not a big deal with a 40 year old language).
If you’re not choosing them for your own projects, then you are part of what you perceive to be the problem. You probably have a good reason, like lack of libraries or general inconvenience compared to popular modern languages. That’s fine; maximizing safety over velocity is the right call for avionics and safety-critical public infrastructure control systems, not the average software project.
