This A's ownership group has never made any effort to keep the team in Oakland. They wanted San Jose from the beginning and the Giants vetoed that so it's just been a waiting game until they found another city they could move to. Lew Wolfe pulled the same shenanigans that the Maloofs pulled -- sabotaging public votes, delaying EIRs for years while pretending that his team was actively pursuing many sites. MLB just did not want the Bay Area to be a two-team market -- they handpicked this ownership group and then steered them toward Vegas. The fire sale the front office carried out over the last 2 seasons made it clear they had no intention to stay. You don't start a 10 billion dollar project (the proposed Howard Terminal site) by poisoning your fanbase to save $50 million.
This really hurts. The A's were the first pro sports team I ever followed. I knew it was over in 2020 when the word got out that Oakland wasn't even going to pay its minor leaguers that year -- the city of Oakland was never going to be able to pull off what Sacramento did to keep the Kings. It was just a fool's hope maybe that they would be forced to sell before they could complete their theft but that ship has clearly sailed now. They'll probably still sell the team and get a big windfall for having a new stadium. They'll always be the third banana in Vegas though and baseball will be done forever in Oakland.
The A's sent me a survey regarding my interest in potentially following the team if they relocated to Vegas about a year and a half ago. Obviously I told them that I was not at all interested and I also wrote them a very long essay about why I think MLB will continue it's decline from the sport everyone once watched (as recently as the mid-90s) to the one that no one under 40 cares about. When you invest nothing in building youth baseball within the local community and focus instead on exclusive television deals and state of the art stadiums filled with expensive luxury boxes and 20,000 less seats than the old stadiums had you're actively shrinking the size of the fanbase who has access to the teams -- most critically the kids who might have become lifelong fans. Most of the elite talent on the field is already coming from Latin America and Southeast Asia now. There's just no culture of youth baseball anymore in any of the major MLB markets because they've let it die. I still enjoy playing the game of baseball but if the institution of MLB collapses under the weight of corporate greed it's good riddance to me. Better baseball is already being played in other countries anyway.
