No idea what Disqus is. I personally try to have one foot in an "alternative" like Hive and one foot in the "traditional" world, with all my weight on the former, ready for them to deplatform me or become useless at any time. This is just in order to reach some people who don't know that these alternatives exists...sometimes there are too many and it's very time consuming to figure out which ones are closer and which are further from ideal.
We can only work with what we have in front of us and try to create something better. I wouldn't judge you for selling anything on Amazon, long as you were active outside of those dirty channels.
Looking forward to your future work, don't let the world get you down!
