The "We" is short for Westinghouse, or at least it was: Westinghouse Steered Stabilized Camera Mount, thus WESSCAM. Then they dropped an "S".
Granted pronouncing the name is ambiguous, Wes-cam or We-scam. But they're known well enough in the industry at this point that it's not a problem for them.
It's the we-scam part that's kinda funny. But of course they don't target consumers at all so that connotation doesn't matter I guess. Professionals just go by the product specs and not brand feeling.
