I personally don't think even that is true.
- Culturally, the 90's were ripe with moral panics over satanism, gender expression, obscenity, etc... That could be a longer conversation, but the short version is that there was a ton of speech suppression happening in the 90's and early 2000's.
- Technologically, our mediums today (as problematic as they are) still allow for a greater ease of communication with a wider audience than they did in the 90's. There are developments online since the 90's that I don't like, and I worry about centralization online. But the earlier decentralized Internet was also very insular and inaccessible to a lot of people, and I think that gets lost from conversations about Internet freedom. More people have access to the Internet today and more people have access to publishing platforms today.
- In terms of mass media, there is again worrying consolidation happening, but it is nevertheless still the case that getting your message out to a wide audience in 2022 is easier than it was in 1990. Podcasts, video streaming, site deployment, etc... is all easier to do today than it was in the past.
Stuff like game development, music production, and so on are also easier today than they were in 1990. That's not to say that they're perfect or can't be improved, but I think back to the Flash boom, and that didn't really start until the early 2000's and it really was a different level of accessibility for making games, including games about political and social topics. In the same vein, a quick reminder that Youtube as a site was not founded until 2005 and until 2010 the max video length was only 10 minutes. Podcasts didn't really start to catch on among the public until the late 2000's. Patreon was launched in 2013, providing a very simple, mainstream way for at least some creators to self-fund their own work by directly interacting with fans.

I think people forget sometimes how new all of this stuff is. And again, that ignores how much straight-up censorship and how many moral panics were happening during that time period, but even just from a technological perspective, if I have a message I need to get out, I would rather do it in the 2020's than the 1990's.
I could maybe see an argument that we're on a technological downtick from the 2010's, but honestly I don't even believe that. Even with all of the platform problems we have online (and it is a problem for our online communication to be so centralized and there are problems about where some platforms are headed), I still feel like almost everything today about media production and dissemination is just so much easier than it used to be. About the only thing I really miss is Flash, and I don't even really think that's a tech problem, I think many of those developers have just moved over to programs like Unity.
Not to say everything is perfect or everything has gotten better, just... I think people have rose-colored glasses that they wear when looking back at those times.
