Except there's a real cost to exodus, and complaining (along with a measurable-yet-easily-reversible impact like turning off sales) is an easy first step that only costs the temporary sales loss. So on the off chance enough people complaining and pausing sales causes the company to change their mind, an exodus that forces the sellers to do a bunch of store-rebuilding would have turned out to be a very inefficient method. It's a statement trying to get the attention of the company. Nobody is claiming it's guaranteed to work. It's a desperate act for before you bail entirely.
