Yes, this is undoubtedly also a factor. Cities offer incentives to these large companies to open offices because they have an impact on their surroundings (see [1]). Workers support surrounding businesses; with the workers at home, these businesses must surely struggle. I can't imagine that the cities are not putting pressure on the large companies to bring workers back to the offices.
