We don't usually share information about sales, as that is confidential business data, but suffice to say we're pretty happy and are going strong for ~15 years, now.
Our users come from all ranges, both in terms of company size (from single-dev shops to big-name Fortune 500s) and target area (mobile, desktop, web, services, enterprise, you name it). Elements is a general purpose programming environment, and I believe there's something to find and like about it for just about every software developer.
For example, while we have a strong focus on sharing code across platforms, the product is nit just about that, a lot of developers single-platform devs still love Elements for other reasons, even if they only care about, say, .NET, or only about Cooca. The multi-platform support is just one of a list of many benefits any individual dev might be attracted to (or not care about).
Projects by no-name companies too insecure to open-source their stack but also too shameless not to flog it every chance they get are not worth even considering. Programming languages that aren't fully and permissively open aren't worth a bucket of spit. And I don't provide my business to the latter, either.

"The opposite, it seems. They got rid of the good parts (the JVM and the industry's best IDE ecosystem), kept the bad (the Java language), added their own lockin-flavoured herbs and spices"
