Every time there's a new thread about Tenet in theaters, the article in question always talks about theaters' inspirational planning and health measures being taken to minimize risk, if they're even open at all. This one even mentions that theaters owners think a July reopening is more likely than June but still not altogether confident about even that. Not a single one of these ever starts from the premise, "By July 17th, movie theaters will be 100% open for business, cramming hundreds of people to a screen at time, and Chris Nolan is forcing them to do this at gunpoint." Yet there are inevitably dozens of posters who act like that's exactly the case. "Chris Nolan is a sociopath." "Chris Nolan wants to kill people for the sake of his new movie." Etc. It's becoming deranged.
If it's safe for theaters to be open at full capacity, then they will be. If it's safe for theaters to be open but at limited capacity, with certain restrictions or health measures in place, then they'll do that. If it's not safe for theaters to open, then they won't be. And in scenarios A and B, Tenet will play; in scenario C, it doesn't. It's as simple as that.
That isn't happening for a lot of reasons, not the least of which is that WB would lose a ton of money on the movie.
