Proton is a company which has been the public face of "privacy on the internet" for a zillion years.
LightSpark is a company that six months ago was selling itself as a "compliance" solution for Lightning.
These are not the same thing.
LightSpark is also hiding behind all of the (maybe formerly) trusted brands like Blitz and Wallet Of Satoshi and Cake. If you visit any of those websites (cake, wos, blitz), they do NOT tell you prominently that there is this one company in LA (LightSpark) who is getting all of your data. It's sketchy. Sketchy things should be discussed, as we are now doing....
