Because the implied part is a bit obvious to any programmer would had to go through the 90s under Wintel domination. They want programmers to use their tools so they can exploit a dominant position and crush competition. They have been charged (and condemned) for abuse of monopolies as late as 2013. I don't trust a company that used to be dominant and evil and suddenly as it becomes weaker tries to play nice. The GAFA are problematic, but their ethos is nowhere as bad as what MS was when it was the dominant player of the software world.
