They lose the ability to claim experimental when it has passengers (and in my opinion also since it is not doing anything particularly innovative... It is "just" a capsule). We dont risk astronauts like that. Spaceflight is risky enough as is.
And the traditional space companies (like boeing) spend so long on design and engineering and testing specifically so that things go mostly right the first time. This is now the third launch and its still having issues despite now risking crew. And that is with several years between launches. Its not a good look for boeing here if they cant get this capsule absolutely rock solid.
Chess has been played for ages with no dlc. Competition against another person is engaging on its own. And chess is a good deep game on its own.
Combine competition with a good game and you get a successful infinite live service game in theory.
Only one or the other and you get a flash in the pan.
