In theory stoicism's precepts are not bad, in practice, however, I've rarely seen them amount to little more than an excuse for obstinacy and ignorance toward legitimate problems and one's own inadequacies. The modern day capitalist tech-bro peddled variant of "stoicism" especially is often just used to justify a retreat inward, and a failure to recognize one's own relationships to others and one's own responsibility. Worse, it is a wholly uncritical "philosophy" that encourages people to accept the status quo rather than endeavor to make it better and change it.
It's one of those traps where the people who need the philosophy the least are most drawn to it.
If you're really emotionally disconnected, stoicism has an intuitive appeal because it justifies what you already do. Although, there a distinction people miss here, observing an emotion and letting it pass is far different from denying the emotion in the first place.
On the opposite side, people who go through life dumping and blaming their emotions on others are very quick to label stoicism as toxic, when it's the philosophy that could help them the most.
It's just one of those things, by definition we can't see our own blindspots.
