Trustworthiness in the platform is dead. Musk uses it like his personal sandbox. Advertisers are quickly pulling out. I don't know how they're possibly financially staying afloat.
Twitter was so engrained in communication that it's difficult for many users to leave (sports, etc.). So, I agree, it's not dead yet, but Musk seems to be doing everything he can to poison the well.
I can't imagine how removing the communications department from a company that specializes in communication seemed like a good idea...
