Do you even understand what censorship or shadowbanning/tagging is?
They cannot censor your content if it is on your own relay.
But that does not mean that other people want to see your content and actively choose to load the content from your relay.
When you use relays of others you of course have to comply with their rules.i mean it is not your relay, why do you think to be entitled to tell someone else what he has to do with his property?
Relay operators do not force you to post content on their relay. yet you choose to do so. So you feel free to use others property yet do not feel that the other person should be free to do what he wants with his property.
Again: but okay. Think that you are the victim and you always will be one.
Running a simple relay for personal use is not even that complicated or expensive. You just have to do it. But who to blame then when your content still does not matter to others, right? So better stay a victim then.
