I think we are in the acitvism bubble. The outrage culture and now this stir the pot activism are fueling certain individuals narcissism to the detriment of the cause and rest of us.
It still is imo. You cannot really gain your 5 minutes of fame (rather than infamy) by spewing hurtful or toxic viewpoints. Self-expression, in this case, imo feels more like self-promotion, which is exactly what narcissism is all about.
If the "activist" in the OP was speaking about some other topic that wasn't as highly publicized and important as climate change, no one would have batted an eye if they got fired for breaking those same rules. But since it is regarding climate change, it can be easily twisted as big bad tech giant amazon firing the good small activist for doing the brave act of speaking out for the climate change mitigation. Whole nine yards with the martyr complex added in the mix.
