But when you're coming from an open source perspective, or just expect tools to be free, like they mostly are for other languages (and should be imo), then those other vendors don't matter as you cannot afford them anyway and AdaCore becomes the only vendor, you can't afford gnatpro either btw.
There will never be an appreciable number of people writing the kind of software that justifies the use of Ada. If your project needs it, the cost isn't a concern.
Ada is a general-purpose programming language with an emphasis on safety and contract-oriented programming. There's a lot of software written in e.g. C++ today where Ada would be perfectly justified, if only it was more widespread and accessible.
You definitely could write a lot more in Ada. The world would be a lot better off for it. Unfortunately, with the way things are going right now, I don't think it will happen. It takes a lot of active convincing to keep people from writing absolutely everything in JavaScript, so I don't think we'll be able to get to a point where Ada's ecosystem will be built out enough for it to be a common general-purpose language.
Green Hills Software is such a excellent producer of software, near perfection in every product...and no the Homepage is not a buy-able product of them ;)

And it seems you overlooked the article. Anyone coming to the comments after reading the article can be forgiven for being confused by the reversal that happened here.
There are still 7 companies around selling Ada compilers, granted not all of them support the very latest standard.
