I use a nostr:npub126ntw5mnermmj0znhjhgdk8lh2af72sm8qfzq48umdlnhaj9kuns3le9ll with their built in marketplace relay active and I cannot use it with my most of my clients. Only with nostr:npub1pu3vqm4vzqpxsnhuc684dp2qaq6z69sf65yte4p39spcucv5lzmqswtfch . 

I would ask the community, why not? Is there a security risk, to me or users? Must I use a domain connected relay with DNS management and am I opening myself to trouble by using my own .onion addressed relay for my own storage of notes and media and for others that follow me to snag that content without going centralized on a nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg nostr:npub1pu3vqm4vzqpxsnhuc684dp2qaq6z69sf65yte4p39spcucv5lzmqswtfch nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 or other branded relay? My thought is that true ownership is keys and data backups. If I don’t have my posts, what do I have? An empty key with followers?

What am I misunderstanding?
