They do implement censorship and safeguards, just in the opposite direction. Musk previously bragged about going through the data and "fixing" the biases. Which... just introduces bias when companies like xAI do it. You can do that, and researchers sometimes do, but obviously partisan actors won't actually be cleaning any bias, but rather introducing their own.
So i understand the intent in implementing those, but they also reduce perceived trust and utility. It's a tradeoff.
Let's say I'm using Gemini. I can tell by the latency or the redraw that I asked an "inappropriate" query.
