That's not enough to excuse the poor results overall. 1930 and 1950 happen to be the most clown-esque tournaments since they had fewer than the envisioned 16 participants, meaning some teams only had two group games. In 1930, all of the British Isles as well as Spain, Germany, Italy and the historically strong nations of Hungary, Czechoslovakia, and Austria didn't attend. In 1950, all of Europe was in ruins after WW2, multiple teams refused to show up again, Germany was banned, and the Italian team had a literal plane crash kill most of their squad
But to get to your comparison: we live in a very different time compared to 1930. The situation isn't comparable, and the World Cup quickly proved a success despite the world being much harder to travel back then. It filled a gap, as it was the first global football event after the very differently organized Olympics. The CWC is something entirely different, it has none of the perks of the World Cup
