PrivacyTools I ask you to please reconsider again to include Skiff Mail in Privacy Tools for the following reasons:
1.- It is open source, so it is auditable.
2.- The email client also implements the IPFS protocol.
3.- Even if we do not consider it as an email option, it can be an interesting option when establishing aliases. To give my example, I only use the 3 aliases offered by Skiff Mail to access public resources (for example, to register in games), while my base and "100% private" email is ProtonMail.
If anything, I think it is convenient to include a warning like "If not used under IPFS configuration this email provider is affected by US legislation, so your privacy could be severely compromised".
Best regards.
