When California encountered power issues, it was easier for Texas politicians (and many of their followers) to espouse malicious soundbites about Commifornia than to empathize, offer support and self reflect on what lessons can be learned and applied locally.
Now that Texas is reaping its own fruits of decades of anti-"other side" politics and political mismanagement it's all too easy for whatever "other side" to treat Texas with the same derision and malice instead of empathy and support.
The government run Texas grid is ill prepared because the responsible parties are more interested in playing division politics than in governing.
Cold and snow are not novel, it's not a technical problem.
