I didn't mention in the post here anything about owning your data, but to respond to your questions here.. 'Ownership' is a pretty meaningless phrase without enforcement and currently the only commonly used form of enforcement is through the court systems offline. In general, Hive isn't sold as a system for enforcing ownership of your own data. Hive is sold as a system where you own your own account, which means that it cannot be shut down or controlled by a central authority or corporation. You have the right to always fork the blockchain and start your own version, so you will never lose your data as long as you are actively participating in the system on a technical enough level.

If I wanted to I can take your content and replicate it as many times as I want and there's nothing you can do to stop me, in fact, I can just pull the feeds and do with them what I want

That's exactly the same as other forms of media and website. Again, Hive isn't sold as being a system that prevents you from doing this.

Do you think the servers used to hold the data you're not holding yourself are incapable of being shut down?

They can be shut down, but like bit Torrent, mirrors will spring up quickly. Despite a lot of effort and court cases, bit Torrent continues.

Do you think an ICCAN domain is incapable of being flagged or removed?

The centralised domain system is still used to run bit Torrent sites after years of trying to shut them down. Even if governments started a 'war on hive', Hive could still continue outside of the centralized domain systems. Private DNS networks already exist and so do web 3.0 equivalents.

if what you did say was true, How does that apply to content that may be deemed unsavory or illegal?

If you are referring to the idea that your content cannot be deleted on Hive, there are some caveats. The top 20 witnesses can convene and reach consensus to remove posts from the blockchain if they are deemed to be a huge problem. To my knowledge this has never happened on Hive and only happened maybe once on Steem. This would likely only ever happen in cases of child sexual exploitation or extreme material of a similar nature. In general, the people who run the network will not act to devalue the network by removing posts. If they did so, then the big stakeholders could vote them out and if the big stakeholders for some reason agreed with the post removal, then the rest of the community can always fork the network and create a new blockchain that includes the controversial posts.
