To chime in, the website IMO lost a lot of personality with this update, any issues in-text formatting is not enjoyable. We need more customization options and not less, so creators can focus on their audience and first impressions. This is important for writers, who need a hook to catch eyes, and for artists working on anything long-form.
Let's pretend we all own little stores, and we want people to browse our wares. What draws people into my store in this example, would be my store-front. Smaller businesses fuel the economy when the wealth trickles down, it creates a rich town people want to live in- it creates a site people want to stay on. I would from a personal stance, reinstate and potentially even add more user customization- that way people stay because all the stores look much, much cooler.
The UI is much sleeker, but in the same light, it looks boring and unfinished. I've coded websites before and acted as an admin on others, as responsive and functional as it has been for the few times I've clicked around, I can definitely say this pushes Tapas further away from being a recognizable brand, and enjoyable site - (On desktop specifically, I haven't used the mobile app.)
TL;DR: Let people customize, it draws in more viewers and makes the entire site's economy much more lively, and minimalism is not a good approach for a site that is anything but minimalist- tapas is sensationalist, it's loud - it has a voice, and a community. Bank on that comfort.
(In terms of copyright, it's always going to be an issue, and the more material you let people source, the more those issues will arrive, but do not fret - for that is unavoidable on any user-driven platform, and reading over your terms of service, I'm fairly confident y'all have that under control.)
