> FOSS started as a counter movement against Microsoft in order to escape from surveillance and corporate control.

??? FOSS was around before that, famously so.

The rise of Microsoft made FOSS more important, but FOSS wasn't a reaction to surveillance and control, when it started even multi-user networks were practically unprotected, and it was quite easy indeed to see what other users were up to.

The phone phreaks were the ones who were worried about corporate control of comms, the FOSS people just couldn't figure out why people were paying for software with the hood welded shut when there was better software available to those willing to help contribute to it.
