They're technically right about *something*.
2008-2020 was a showman era for politics.
08 was revved up as hell with Obama famously taking advantage of online popularity (Ron Paul also had a huge chance based on memes that was basically ruined by the RNC borderline sabotaging him.) 

2012 was when we really saw the first big online meme usage for a presidential election with democrats taking advantage of Romney's gaffes like Big Bird.

Trump took this to the next level and politics were basically a show. Biden by comparison, built himself on being boring as he possibly could and coming off as a "safe" option politics wise.

Reddit had become used to seeing some form of "Trump bad" news daily for 4+ years. Biden news only comes around every few weeks and is tame in comparison. I believe it is largely because Biden's persona is boring, while Trump was extremely polarizing. Good entertainment can make you laugh, cry, jump for joy, or seethe in anger. The one thing it cannot do is *bore* you. That's why Biden, and many other politicians have an air of "not doing much." They're definitely doing things, but they aren't exciting enough to get many clicks and likes.
