https://www.cbsnews.com/news/mlb-oakland-athletics-may-leave-city-for-las-vegas-stadium-lawsuit-2019-10-08/Gist of the situation is that the A's are trying to acquire land for a new ballpark, and the city is saying that any land deals must first make room for public space and affordable housing. Given the housing crunch in that area, it seems that bulldozing both the Colosseum and the Oracle Arena next door to build housing might make more sense than building a new A's ballpark.
The crazy part is that the owner isn't asking for public funds to build the stadium.
