Customer volume for Starlink is arguably more valuable to SpaceX than profit per customer.
Dangerous also because the media industry insists that ISPs permanently cancel the service of customers after multiple unproven allegations of copyright infringement and without a single conviction. So far, the courts have been completely agreeing with them and ISPs who refuse to bow to the wishes of the media industry and terminate these users are being sued.
Anyone can lose the ability to have an account at the only ISP they have just because some third party P2P snoop, hired by a movie studio, forwarded a DMCA notice to their ISP with their IP address on it too many times (with "too many" being entirely unspecified in law and up to whatever the ISP thinks won't get them sued). Those third parties haven't exactly always been so careful about avoiding false accusations either. Actually doing anything to deserve a DMCA notice isn't required.
