I don't find it surprising. The orbital launch industry is small, but it requires large risky long-term investments. Until a few years ago, SpaceX revenues were relatively flat at ~$2 billion/year. There has been significant growth since then, but more from Starlink than from external customers.

If you're interested in money, there are better investment opportunities around. And if your angle is national security, the ~€500 million/year needed for a program such as Ariane 6 is little more than a rounding error.
