So my source on this is Tuxsudo, who did an interview with Watchman,
Apparently watchman censored the interview post-recording, saying that "cake wallet didn't fit his vision" or something along those lines.

I am speculating that the reason is so watchman can sell courses.  Now can I be wrong on the real motivation? yes.
If you have a time when watchman taught Monero, I'd love to hear it.

Now regarding doug, you are entitled to your opinion sure.  I think though he's doing a lot of good education-wise with getting good people on there
