I've seen similar, and don't doubt it. I just keep wondering: how does that work, mechanistically? A coronavirus infection doesn't protect me from influenza: it should be perfectly possible to be infected by both. How do they compete?

Influenza and coronavirus 'compete' by forcing people to alter their behavior, thus removing potential carriers from the general population before the other virus can reach them. The more infectious virus wins this competition.

The flu isn't very infectious compared to even ancestral covid; its R number is normally reckoned at well below 1.5, so covid suppression techniques (which pushed covid's below 1 in many places last year) would have been pretty hard on it.
