This kind of site is a core example of why people are skeptical of the "false choice, we can open up responsibly" narrative. In practice, if a graphic designer makes a nice-looking chart where a state is red, that seems to be treated as a conclusive argument that opening up isn't responsible. The site doesn't appear to have any specific argument why Texas is wrong to think it can safely open up, just fixed numerical thresholds which Texas hasn't hit.
Those thresholds seem reasonable to me. The fact that so many states are "red" on the map (not ready to reopen, not the political "red") is indicative that we wasted a lot of time in the US not getting ready. This failure is going to continue to cost us billions of dollars, to say nothing of lives lost.
