The change of hands when it comes to owners has had major repercussions. Originally WB under AT&T was going to spend big on HBO MAX, they reached out to MBJ because they wanted him to create something for their service, and the powers that be had lost all faith in Superman. That led to just chucking shit at the wall to see if something would stick, so Abrams gets to do a black Superman movie, MBJ does a black Superman HBO Max series, the CW gets a white married Superman, MAX gets another white Superman cartoon, a Latina Supergirl takes Superman’s spot in the Hamadaverse. Bringing it all back to Jon, who is after all the subject of this thread , this was also the same time where WB was supporting Didio’s 5G reboot which would replace Clark with Jon as the new “main” Superman. Would’ve been some synergy with that move because Bendis was presumably pitching his LoSH animated series which would have adapted his run and featured Jon as a lead if not the lead.
Then of course AT&T sold WB to Discovery and Zaslav had much different priorities. 5G gets killed around the time of the Discoervy buyout because nobody wants to invest money and support into a reboot before the new ownership takes over. The old HBO MAX leadership gets purged leaving a bunch of MAX projects - presumably including the Val show - up in air, Hamada gets the boot and he was the main supporter for Abrams/Coates, and Gunn takes over DC with his big project being a Superman reboot (which if nothing else tells me Zaslav doesn’t have much enthusiasm for either of the black Superman projects if he was telling Gunn to give him something new).
If DC hadn’t made Jon bi he probably would have been deaged by now, he, Jace, and Yara are phantom remnants of the 5G pitch. You’ll notice they quietly abandoned bringing Jess Quick over to the main Earth like FS advertised would happen. Clark is back to being the one true Superman with other contenders demoted to supporting him in Action (Conner, Kenan) or relegated to third string titles (Jon, Val).
