It makes plenty of sense. On https://prism-break.org/en/all/#email https://prism-break.org/en/all/#email, they state "For more email providers, take a look at Privacy-Conscious Email Services. Please decide for yourself whether if you trust them with your data. For more discussion about safe email providers, please see issue #461.". They even state that Thunderbird is a "Extensible, cross-platform email client.". The implied idea being to use Thunderbird to access a "Privacy-Conscious Email Service". I use Gmail as an email client more than than I use it as an email provider because it has an External Accounts function. I apply Google's "App Script" system to my email to do things that you could do in Outlook's full-fat client or maybe in Thunderbird with some extensions.
