The bad side of technology (*), those that wanted face to face events are now denied it. The benefits of that are now gone.
Online in addition, ok, but canceling physical events, including one already scheduled and that people have already made arrangements for (travel, time off, etc) is bad.
People can socialize and network at a physical event, there are somethings online only lacks.
(*) Technology has also caused the loss of video stores, CD stores, so many things are hard to buy locally now. Technology should add options, not destroy them!
