@maija I'm in favor of freedom.

You should be free to choose to not publish software and not make it do others computation and use it privately.

It's only if one chooses to publish software, or make it do others computation that the source code under a free license should be available.

If you have your own private editor you use to edit config files, you should not be forced to publish that editor merely because you used that editor to modify config files of some other software - but the SSPL is written to demand the publication of everything on such server and not just the relevant source code of the software.
