You're response amounts to "Okay, so what if it was created and funded by an Israeli company known for espionage? They spun it off into a non-profit, which somehow removes any connection between those two things now."
As to Element, they are, in their own words, made up of ex-Matrix Staff.
They're legally distinct entities if that matters, but they're still from the same likely compromised institution.
If you like Matrix and find absolutely nothing concerning about the connections of the two most influential entities in that space, than by all means, carry on.
For myself, I'll stick with XMPP or Deltachat.
