Some of the big things are loss of local advertising opportunities. In many communities, these are the only spaces in which a small business has the ability to share information and services being brought out from municipal governments or through provincial or federal offers. Those disappear, as people don't have access to that information as easily as possible, especially in, as you said, rural and remote communities that have low broadband connections as well.
For the music industry, in many places it's often a meeting point for communities to come together. They'll offer out spaces or opportunities for festivals or local events, and these just wouldn't happen, because there's no space for people to gather around that.
