What we also don't know is the companies financial situation. Keeping people on when they can't be afforded can be a way to make a company completely collapse. I was in two startups that would have collapsed completely, without layoffs, around the time of the last recession. This is why the "keep x months of salary" are rules you strictly follow.
Recognizing the impact of an action does not mean you're entirely responsible for it.
This is besides Patreon giving their former employees a license to goof off on their dime for 3 months. I can’t imagine anyone at Patreon being so hard up that 3 months pay and insurance to look for new work is enough to break the camels back.
Those who are hired to Patreon and similar companies arent people who would end up unemployed if they are laid off. Those people already have to turn down recruiters who try to poach them every week.
We don’t know everyone’s unique situation, even if they did go beyond what most companies do.
