Oh, come on... They are enabling you to use LLM is you want to. They are not forcing anyone.

And here is why it is better than most alternatives out there... An Open Source AI, build with transparency and ethics should be something to be exited about - for all who use LLM... For the record, I don't. I don't have any use for it, my brain works fine... But I have an exception, and that's my own private LLM, running only on my machine...
So, please take a chill pill, and do some research before yelling "WOLF!"
