In general this tends to be true. However, in this case I'm not so sure. Modular seems to have garnered a lot of investment - probably orders of magnitude more than the Julia community has been able to get. There are a lot of nagging problems in Julia (startup times - though that's gotten better recently, ML kernel performance, and executables come to mind) that could have been easily fixed if they had the money to throw at them. Since they haven't had that kind of investment people who kick Julia's tires tend to see these things as built-in limitations and move on.
