The legions of open source advocates are necessarily socialists (at least with respect to information sharing in general and software specifically).
Socialism is central to modern software development. If it was not then there would be no "free software foundation", "no open source", no plethora of "copy-left" licencing. I don't say this as if it is a bad thing. Clearly we are centuries of person years ahead software wise as a result of this socialism.
This individual behavior stands in stark contrast to the behavior of most tech companies as a whole that are clearly not "leftist". There is nothing leftist about NDA agreements, confiscation of IP and anti-poaching agreements to control wages. There is nothing leftist about dark ui patterns, shifting terms of service and harvesting of personal information and micro-transactions.
