Vegans used to not own pets as that was deemed immoral. And now they do. The goal posts keep moving.
It's still human dominion over animals. And veganism is still veganism. e.g., don't tell me that "some vegans decide it's OK to wear leather" because they're not "a collective entity" or something like that. Veganism is very much a black & white ethos. There is no acceptable gray area for veganism.
