The blame China syndrome (ha) is baffling, given the many competent measures they took that were a fairly good model of how to deal. The conspiracy theories (like Pompeo's idee-fixe about a man-made pathogen) are entirely driven by partisan posturing and not by the science.
My initial thought on masks (which was based on past training in biology labs) was influenced by the perception that a lot of people didn't understand how to wear them or have sanitized hands when adjusting/removing them. I came around on mass usage, partly owing to Bo's nuanced points about containing coughs and their overall mnemonic value. My own community protection is still focused mainly on social spacing at stores, using sanitizer after I've touched merchandise and checkout pads and before I touch car keys or surfaces in the car or put on sunglasses. My lab experience tells me hand-to-face is still the number one pathway.
