No, it's not expensive, you're right. But it is for me in total. I use Apple products and have to pay for the stupid cloud when I want to work flexibly. I pay for the rental (!) of editing and graphics programs, pay again for cloud storage, because I shoot at least in 4K and I have to upload in 4 k, otherwise the loss of quality is too high. Videos often still don’t  look good and that annoys me. I pay for apps find useful but mostly for Content creation .. 
I'm not stingy, but I would like to keep the costs low for services that I only use occasionally . I would gladly pay for a well-functioning client, but so far there isn't one that has all the features I would want. In general, I think - please don't get me wrong - that it should be super easy to upload long content to any Nostr client. That would be a super power. Any teen can create high quality videos these days, few apps offer to share longer or high resolution content easily. For me, that's one reason why TickTock is still successful. 
Also I avoid KYC where ever I can.. Anyways, I think your offer is the best at the moment.
