Biden did not “strike it down”, he halted all EOs not in effect so their administration can review them (see: the first paragraph of the linked article). Instead of re-issuing an EO, something that can be withdrawn on a whim (see: your post), Biden did the actual hard work of working with Congress to help pass the Inflation Reduction Act. The $35 cap is now backed by law rather than by diktat. Trump took the lazy path and issued the EO in the last days of his Presidency - a Presidency he spent quite a long time using to try and repeal the Affordable Care Act.
Try understanding the issue instead of spamming MAGA talking points.
