Mad Magazine was already losing money hand over fist and only kept around because no one wanted to be the executive who killed Mad Magazine. As it stands, turning it into an all reprint book was probably the only way to truly "save" it at this point, as the Trump bashing could be seen as the final straw that broke the camel's back since it didn't deliver a sales boost like it was supposed to.
Also, Biden's now announced he has canceled his inaugural parade event. My guess is that he's realized the optics are so shitty with the way that the Democrats are all "rules for thee but not for me!" with the lockdowns, combined with the fact that Biden will have zero honeymoon period, that he doesn't want to deal with a day one scandal about how the Democrats were being hypocritical shits allowing a huge parade to celebrate Biden's coronation only to then, once the public spectacle was finished and Biden sworn in, immediately put the nation under a draconian lockdown with a vague end date; all so that Biden and his media cronies could boast about Biden having a bigger turn out at his inaugural than Trump, COVID be damned, THEN only do a national lockdown once Biden had his inaugural and could use it so that the left could further emasculate Trump.
