Depends on who you're talking about in organic context.
For instance, if you're talking about the Instagram Explore page or the Tiktok For you page, its all marketing. Literally nothing is real, everything is made to maximize engagement.
If you're talking about your followers who you know in person, that will be 80% authentic at least.
Some don't like them on ideological grounds (centralization of a sizable portion of the internet), some don't like how Cloudflare can make your browsing experience miserable if you use TOR or turn on Firefox's anti-fingerprinting features (and Cloudflare is s major part of the reason these features are off by default)
I don't like Cloudflare skirting the responsibility of a hosting provider by claiming to be a neutral third party similar to an ISP instead of a company paid by their customers to distribute their content on the web.
Also them not taking a stance on housing despicable stuff like KF that literally bully people to their deaths.
