> given the size and budget of CERN, it's probably cheaper for them to develop things in house It's not just their size, it's that they're doing something that no one has done before. When you're building a me too product or even a version 2 of something, maybe buying makes sense. But when you're doing something for the first time, and you're not even sure what will work (e.g., CERN), by definition it's impossible to buy. If you could buy it, someone's already built it. Generally, the more uncertainty around the business model and potential solutions, the stronger the case for building. Conversely, sometimes the larger and more bureaucratic the institution, leads to slower iterations and experiments. Because of these two seemingly contradictory points, when a large company wants to do something unknown and relatively uncertain, they buy an entire company, provide them resources, but try no to interfere too much (see, e.g., GM buying Cruise).
