As someone who chose a team almost at random 15 years ago, I would say do your research and then make a decision. I chose to follow Chelsea when I had no idea what an oligarch even was and I had to deal with the complexity of loving a team that was funded by someone who stood for everything I was against. If who the owners are matters to you then definitely take that into consideration.
When you have a choice and are aware enough to know you have a choice, best to make the best choice for yourself.
