I'm personally still lamenting over 4chan being taken over by the exact same people it used to despise.
Chanlords in the 00's-early 10's were -rightfully- clowning on wiggers/guidos/tapoutbros/machobros/swaggots/tryhard wannabe gangster alpha douches & phony, corporate, attention whoring mallcore groomers/scene kiddies/adjacent.
Seemed like much of the site's culture back when I initially entered the picture ('08-ish) served as a rightful cynical foil to all the trashy bullshit going on within the zeitgeist of the time (albeit admittedly expressed/engaged in an emotionally immature/cringe way in itself in retrospect; and the chaos within serving as a smokescreen for actual nefariousness ofc.)
Now it's being ruled over by today's respective equivalents ("le ebin pepe" manospherean alpha male top G Andrew Tate-stanning alt right /pol/tards + fantanodrone raptimist fuccboi hypebeast /mu/tants [typically are far left, mostly siding with BLM - just to live through ghetto black culture as a means of satiating their own masculine insecurities - and using said brogressivism as a vehicle for bullying/reactively abusing square/nerdy/unremarkable/autistic beta male white kids] being today's machowiggers, and obnoxious Y2K hyperpo[o]p rawring 20's discord mod tucute MtFs being today's mallcore poser cringelords.)
Gamergate + phoneposters + botfarms + zoomer pewdiepie kiddies & their consequences. I'm only still hanging around by inertial habit/addiction.
