Literally so: 2 of the 3 changes they highlight are "movement" within the margin of error on the estimates (in both cases, only a bit over half of the MOE). So just from sampling error, there is very low confidence that a change in the direction stated in the headline actually occurred.

A responsible headline would be "More Californians moving to Florida", without mentioning the "changes" in California-to-Texas/Arizona flows, which from the data cannot reliably be said to have occurred.

Cherry-picked data points combined with basically meaningless anecdotes. I'm sure there are some meaningful patterns overall but they're hard to reach conclusions absent a broader picture with percentages as well as absolute numbers over time.

A majority of these sort of posts seem to be mainly to generate clicks from people who have an axe to grind about California, they offer no real insights.
