You are mostly correct, with the exception of Mobile. I can't find any open source version of it (there are free versions of everything else), it's seems unique and surely has some value.

I'm not sure how people came to believe strongly that SFT's software are all best in class. All I've seen is Kay's say-so - there are no independent reviews to verify that, or best-of lists that name any of the SFT products. And VChat is too little and way too late.
