Tubi TV and Youtube both host various Hasbro cartoons. Both are freely accessed and ad supported. Any basic TV package (barring straight antenna) includes channels like USA Network, SyFy and FX, all of which regularly air the films from Transformers and GI Joe.
I dunno what to tell you, media might be changing slowly, but at least it's still accessible. Even the folks that DON'T get one of the streaming services can watch it on the company website. It's a vehicle for the toy line after all, they need to make an effort to make it as consumable as possible.
As long as the the cartoons are profitable, then they'll make more. The media it's shown on is completely irrelevant. I say that as a guy whose earliest surviving memory is a big red truck turning into a big red robot.
