You might as well say "Lex will appear before MOS2 is made, then stop appearing!" And David Ayer didn't give a damn about "threats" to his version, it's not even his call to make.

The total embargo era is over. The only thing we had confirmed was WB execs asking Arrowverse showrunners to remove Deadshot because they were promoting Will Smith as Deadshot at the time. Once SS was out, they were allowed to bring him back in. Considering the difference between performances and the desire not to have comparisons, it's completely understandable. And that's it. That's what we had confirmed.

Superman is on Supergirl despite his promotion before JL. Deathstroke is on Arrow despite him being teased as the villain for "The Batman". And if you say "well, the movies aren't made yet", then the same is true for Man of Steel 2. Unless WB execs directly come to Berlanti and ask "don't use Lex this season, we're promoting Jesse as the main live-action Lex this year", he can use whatever is approved. There is no distinct "rule" on it (like in the Bat-embargo days) other than specific executive demand (think of Blue Beetle and Kord Industries - they were supposed to appear in Arrow, but asked not to, because the WB were making a movie - except, they weren't, at all, so that was pure meddling). Barry's appearances before were practically cameos.

Also it was confirmed Grant Gustin was going to be the Flash in a 2015 Justice League movie that was cancelled.

Yes, Lex can appear, but just like that Blue Beetle situation, as long as they claim they will use him, TV shows aren't allowed to have the famous villain on screen.
