No a big part is that the buildings are ugly and transform the character of a place that folks grew up in. Maybe focus should be put on beautifying these buildings in some way
Even if invisible they would not be a popular neighbour because they are a very overt reminder to the poor people around them how uneven the wealth and political power distribution is between them and the tech exec owners?
People in my area are complaining about data centers being built in rural fields and on former aluminum plant and power plant sites. The debate has become pretty detached from reality. What remains rooted in reality mostly comes down to electric bills / power consumption and the fact that, as everyone is saying, it's the only way for people to push back against big tech billionaires.
I don’t see how they are any uglier than any other industrial facility. That’s really what these are and it’s how they should be viewed. Typically most people don’t want to live next door to a factory, but there are some places where it’s appropriate to build them, often remote land or former industrial sites (brownfields) where you don’t want housing due to previous contamination.
