We encourage users to use privacy-protecting email addresses. But yes, Rizful is a centralized service provider -- but there are key differences:
1. We're honest about who we are and what we are doing. When you use Wallet Of Satoshi or Blitz or Breez, you have to dig into the code (or worse) to realize that actually, these companies are just "fronts" for LightSpark's API.
2. We don't ALSO centralize tons of data from big players like Coinbase. With LightSpark, not only are they hiding behind lots of smaller players, but they also get a ton of data from bigger players like Coinbase.
3. LightSpark literally marketed itself -- until it for some reason switched strategies about six months ago -- as a "compliance" solution for Lightning. They are neck-deep in KYC, and their CEO, David Marcus, is a rabid supporter of Isreal, a country with literally the worst human rights record in the world. LightSpark is the LAST company that ANY freedom-focused Bitcoin company should be doing business with.
