Z:gnu-www-ja-who-does-that-server-really-serve--1155c7-Unlike proprietary software, S/en

Unlike proprietary software, SaaSS does not require covert code to obtain the user's data. Instead, users must send their data to the server in order to use it. This has the same effect as spyware: the server operator gets the data&mdash;with no special effort, by the nature of SaaSS. Amy Webb, who intended never to post any photos of her daughter, made the mistake of using SaaSS (Instagram) to edit photos of her. Eventually  they leaked from there.
