> These tools are bad, objectively! They give inferior user experiences, and waste resources (ever more important now with RAM prices what they are).

They can be "bad" in some dimensions (as you mentioned) while being "good" in others (dev productivity).

These frameworks didn't become popular for no reason. They have value. The parts that are "good" can easily outweigh the parts that are "objectively bad" when they enable a smaller team to get things out the door they would have had trouble shipping otherwise.
