I suppose the problem is that paying users are subsidising free users. I know our company has about four paid accounts but we tell all our clients to get free accounts so that we can easily share files. It means that there must be a 10:1 ish ratio of free to paid accounts which probably prevents them from dropping the price. Arguably though, the service would be less valuable if everyone had to have a paid account before you could share files with them.
