I am very inspired by such brave people. However, I am not ready to do this on my own, because I am afraid of physical violence. Now these are hard times, most of the information is subject to strict censorship, so you can support your ideas and share the news either here or in an anonymous application like Utopia p2p https://u.is/en/ . I sincerely believe that everything will end with the victory of the truth.
ProtonVPN is reliable, but depending on how many resources you have you might want to buy a cheap used laptop with cash from a computer store, don’t set it up with any personally identifying details, never connect to any networks at or near your home, and travel some distance to post the video/podcast using public WiFi AND your VPN.
This is the safest way I can think to do it; you will also want to be conscientious of how and where you travel - crime investigators will use past known posting locations on a map to construct a circle around your most likely residence... so don’t post from places in a circle around your residence, travel on public transit and pay cash for your tickets, wear a mask and clothing you will not otherwise wear out.
