Anyone in here claiming to use "old.reddit.com" -- so you're a non-logged-in lurker? and have a weird sense of entitlement for how the site should serve you? The old UI is great yes. But if you can't be bothered to log in as a normal user of the site (and set your preferences to the old UI) your opinion loses alot of steam.
Log in -> set preferences -> surf reddits with www. urls like normal.
