A lot of people people contributing to FOSS are volunteers. The calculus of working on stuff for free involves an assumption that your worst-case outcome is you make $0. This act's punitive fines change the worst-case outcome to somewhere around -$9999999 or more.
If you work on any programming project at all in any capacity:
- Are you confident your work doesn't fall afoul of this?
- Are you confident they won't decide to come after you anyway for insane political, bureaucratic or "seeing-like-a-state" dysfunctions?
- Are you willing to bet millions of dollars in potential fines that your answers to the previous two questions are correct?
