Well, I've been personally lied to about privacy claims by at least Google, Meta, Amazon, Microsoft. Some of which has been observed in courts. OpenAI communication has obviously been dishonest and shady at times if you keep track. All of the above have fallen in line with current administration and any future demands they may have to pin down or cut off anyone opposing certain military acts against civilians or otherwise deemed politically problematic. DeepSeek's public security snafu does not instil confidence that they can keep their platform secure even if they tried. And so on.
Fool me twice, you can't get fooled again.
