Anime might be challenged, but manga/manwha is pretty safe because its got basically a bottom bin bar of entry.

Some of the most popular manga of the last few years started as Twitter posts, basically our version of webcomics, and only got picked up based off pure popularity there. But plenty of them did full runs as just Twitter comics to completion and were no less for it.

So while webcomics never got "mainstream" enough in the West to be really considered anything but novelties, manga outside the magazine industry is already grown to be a huge market and they literally cannot control it short of full Censorship on all social media sites (possible but a huge endeavor).

If the Woke were smart (they aren't) they'd start cracking down on scanlators instead, to try and stifle the flow of non-mainstream manga into the West. But they don't even realize that's the true threat to their control, and god love those autists for it.
